An example of how QuickPipe assists in the design of a cooling system

Search Keywords: “QuickPipe“, “Pipe Design“, “Pressure Loss“ in iPhone App Store

To show you how QuickPipe can facilitate the design and reduce the time to market, let us take the following case as an example for demonstration. 
This is a complete cooling system which consists of an outdoor dry cooler, a control unit with pump, manifold and cold plates to transfer the heat from a customer facility to outdoor.
The customer facility is a device that has 6 IGBT boards inside and each board has a heat dissipation of 3.6kW. 

They are placed one on another and a cold plate with running water will be attached to the IGBT to absorb the heat and cool such IGBTs within the temperature limit.

There is a control unit with pump inside to generate the required water flow rate for cooling. Of course at the design stage the capacity of such pump is to be determined based on the overall pressure loss of the whole pipework. The water being heated by the IGBTs will next go inside the coils of an outdoor cooling tower. The cooling tower is designed so that the water leaving it will be 30℃ at the maximum.

The parts of such system are arranged in position so that the pipe length from the cooling tower to the control unit is around 11m, from the control unit to the manifolds is 3m and from the manifolds to the cold plates is 1m.

We will start from the IGBT boards to determine the necessary flow rate of the overall system. As shown in the figure above, there are 9 IGBTs on each board. It is a common practice that the engineer will use any of the CFD software to help determine the required flow rate into such cold plate. The design target is usually to keep the temperature of any IGBT under the allowable limit. By using such CFD software, we determine that the flow rate into each of the cold plate should be at least 11.355LPM.

With such number in mind, we can obtain the leaving water temperature from the cold plates by QuickPipe. Since the flow rate is known as 11.355LPM, we will use Page 4 of QuickPipe for “Heatload <-> ΔT” calculations. Before jumping into Page 4, we would suggest that you check the page of “Unit Setting”  first to make sure that the temperature is in ℃, the volume flow rate in LPM and the heatload in kW. Since the entering water temperature to the cold plates is 30℃, we first change the index of fluid to be 6. We then input the initial temperature as 30degC and the volume flow rate as 11.355LPM. Since we already know the heat absorbed by the water is 3.6kW, we can tap the segmented control to the top right of the page as “Heatload to ΔT” then input 3.6kW as Rate of Heat Absorbed. Immediately after you complete the input of 3.6kW, you will see 34.57019degC as the resulting final temperature. 

Since both the flow rate and temperature are known to us, the next step would be the determination of correct pipe size for each segment of this system. On the cold plate itself, copper tube of Type K is often used as the cooling tube embedded. Therefore we move on to Page 6, the “Pressure Loss of Water” to determine the correct size of the pipes/tubes. As we move the slider bar of “Index of metal tube” from 1, we will see the “Rec. Max Flow Rate” of index #1 is 6.8963LPM, that of index #2 is 11.98LPM and that of index #6 is 73.394LPM. 

As we already know the flow rate of each cold plate is 11.355LPM, index #2 or 3/8” Copper tube of Type K is what we want. Similarly, the overall flow rate of six such cold plates is 68.13LPM and index #6 or 1” Copper tube of Type K is also what we need. Should the customer prefer hoses for the connection in between the control unit and the manifolds, we can change from “Metal Tube” to “Hose” in Page #5. In such case, we will see the “Rec. Max Flow Rate” of index #2 Hose is 10.812LPM, that of index #3 is 18.533LPM. 

Because of the fact that the inside diameter of hoses is smaller than pipes/tubes of the same nominal size, the recommended maximum flow rate will be smaller. Here there is no definite answer to choose #2 (3/8”) or #3 (1/2”) hoses since the “Rec. Max Flow Rate” is based on the empirical rule that the fluid velocity inside pipes/tubes/hoses should not exceed 8ft/sec. Since we require a flow rate of 11.355LPM which is just a little larger than 10.812LPM, #2 (3/8”) hose should be a better answer considering the larger bending radius of larger hoses.

So far we’ve determined the temperatures and the pipe/hose sizes of each segment of this system. We can generate a table similar to the one below.

Segment #	Description	Tubes/Pipes/Hoses	Length (m)	Volume Flow Rate (LPM)	Predicted Pressure Loss by Quick Pipe (mH2O)
1	Control unit to manifold	1” hose (Couplings on both ends)	3	68.13	0.702104
2	Manifold to I/O of cold plates	3/8” hose (Couplings on both ends)	1	11.355	0.855244
3	Inside cold plate	3/8” Copper Tube of Type K (with 6 internal turns)	1.4	11.355	1.468238
4	Cold plates to manifold	3/8” hose (Couplings on both ends)	1	11.355	0.855244
5	Manifold to dry cooler	1” hose (Couplings on both ends)	14	68.13	3.276486
6	Dry cooler to control unit	1” hose (Couplings on both ends)	11	68.13	2.574382
Overall Pressure Loss excluding the manifold and dry cooler (mH2O)					9.731698

 Screenshot of #1:

Screenshot of #2 & #4:

Screenshot of #3:

 For #3, there are 6 turns inside the copper tube as marked by the red circles in the figure below. The pressure loss of such copper tube inside the cold plate could be considered as a straight copper tube of 1.4m along with 6x of 90° standard ells.

Screenshot of #5:

Screenshot of #6:

This way we easily obtain the overall pressure loss we want. After some more calculations on the pressure loss of the manifold and the dry cooler, we can then select the pump with the required head to overcome such overall pressure loss and make sure such system can fulfill the cooling task as what it is designed to.

Where is QuickPipe based from and how well it predicts the heat absorbed/released and the pressure loss?

Where is QuickPipe based from and how well it predicts the heat absorbed/released and the pressure loss?
As we all know that the change in internal energy of incompressible fluids at constant pressure is
Q =mCΔT
Where
Q is the change in internal energy
m is the mass of the fluid
C is the specific heat capacity
ΔT is the change in temperature

For engineers dealing with fluid cooling/heating, this is the most frequently used formula to determine either the temperature change or the change in internal energy (aka heat absorbed/released). It may sound easy to memorize certain values and calculate it by tapping on an electronic calculator. However, the selection between SI and imperial units and choices of various heat transfer rates per unit time will make the calculation involve with more numbers behind.

QuickPipe is such a tool that you can simply select the units you want to use, input the numbers and you will get the resulting number you want. The app itself will help verify whether the input values are valid or not. Here is an example to demonstrate how it works.
Here is a question from the link below on the heat absorbed by ethanol.
http://www.answerbag.com/q_view/736406

We can obtain the result easily from QuickPipe by the inputs of initial temperature, final temperature and mass of ethanol respectively on Page#1. If you find any unit is different from the question, you can simply go to the second page from the bottom to enter “Unit Setting” page for unit changeover.

However, when you input 89.9℃ into the initial temperature cell, you will see an alarm message popped up saying that the initial temperature cannot be larger than 79℃.

Why? A sentence inside the link below answers the question.
http://www.ucc.ie/academic/chem/dolchem/html/comp/ethanol.html

The boiling point of ethanol is 78.3℃ only under typical condition. Therefore, ethanol at 89.9℃ should be in gas state rather than liquid anymore. With QuickPipe, you can easily make sure any question won’t deviate from the characteristics inherited from the nature.

With a valid question as is in the link below, we can obtain the result like a duck to water.
http://www.ehow.com/how_6641786_calculate-heat-absorption.html

Here we input 20℃ as initial temperature and 50℃ as final temperature and pick the fluid at index #5 which is water at 20℃. After we input the mass as 250g, we immediately obtain 31,372.5J as the total heat absorbed.

The result is pretty close to the 31,380J shown in the website. Actually, QuickPipe is even more precise than the number of 31,380J since it has a complete database of specific heat capacities and densities of water from 0℃ to 100℃ at a five-degree interval. That’s why we provide water at different temperatures as selectable by the user to pick the one closest to the range of temperature entered.

        We refer to the following link for the properties of water at different temperatures.
http://www.engineeringtoolbox.com/water-thermal-properties-d_162.html

        So far you should understand that QuickPipe is based on the exact characteristics publicly available that the user can easily examined. The most important two values of specific heat capacities and densities can be easily found at The Engineering ToolBox or Wikipedia.
        Here we have another example dealing with a running system which is frequently encounter in chiller industry. Example 3 in the link below is what we are targeting at.
http://energyexperts.org/EnergySolutionsDatabase/ResourceDetail.aspx?id=2835

As usual, please kindly check in the “Unit Setting” page of QuickPipe that the temperature unit in “degF”, the volume flow rate is in “GPM” and the heatload is in “RT” (aka Refrigeration Ton). Next, we should use page 4 of QuickPipe for calculation since this is a “Heatload <-> ΔT” question based on volume flow rate. After that, simple tap in the numbers of “45” into initial temperature, “55” into final temperature and “10” into volume flow rate. Here we get 4.178869 RT as the rate of heat absorbed.

You need simply multiply this value by the factor of 0.8kW/ton specified by the question then you obtain 3.32kWh as the results.
        The discussions above should give you confidence on the results obtained by QuickPipe on Page #1 to Page #4. We welcome you to test this app intensively before you use it as a daily tool for frequent calculations.

        Let’s move on to Page #5 which is a database of both metal tubes and plastic pipes. The page itself should be quite explanatory as you can pick either metal tube or plastic pipe from the segmented control button from the top right of this page. After that, simply change or input the pipe index from the slider bar or the text field and you will see the characteristic numbers of pipes/tubes. Please kindly visit the link below for the list of all pipes/tubes available in QuickPipe.
http://clydestudio.blogspot.com/2012/05/list-of-all-pipestubeshoses-available.html
        Of course the major benefit of using QuickPipe is that you won’t need to do unit conversion by yourself. QuickPipe does it for you and you need only change the units in the “Unit Setting” page to your favorite ones.
Now we will move on to another major topic of pressure loss calculation of water in pipework. In QuickPipe we predict the pressure loss with water as the only fluid. This is because water as the fluid for pressure-loss calculation is the best established database as compared to other fluids. Should you deal with fluids other than water intensively, we would recommend you consult professionals with such expertise to learn the best prediction model for pressure loss. Here at Clyde Studio, we welcome more feedback from you so that in the future, we might be able to establish such database of other fluids into QuickPipe.
With water as the fluid, all the pressure loss calculations in QuickPipe are based on the famous Hazen-Williams formula which is a widely-accepted formula for such prediction. For those not familiar such formula, please kindly visit the link in Wikipedia for further details.
http://en.wikipedia.org/wiki/Hazen%E2%80%93Williams_equation
Here we won’t elaborate much on this formula but we will show you how we predict the pressure loss as compared to similar databases available on the internet. The first example is the pressure loss of Type K, Copper Tube. As shown in the link below, the pressure loss (psi/ft) is 0.138 with Type K, nominal size 3/8” at 2GPM.
http://www.engineeringtoolbox.com/pressure-loss-copper-pipes-d_930.html

A similar value of 0.13 is shown in “The Copper Tube Handbook” published by Copper Development Association. We obtain 0.1299254 with QuickPipe which is the same as “The Copper Tube Handbook” with marginal difference.

With a larger pipe size, the pressure loss (psi/ft) is 0.004 with Type K, nominal size 4” at 120GPM. Exactly the same value can be obtained from “The Copper Tube Handbook”. We obtain 0.0041766 by QuickPipe and this should be the same as both references considering the rounding of digits.

The second example is the pressure loss of 3” Cast Iron Pipe at 42GPM. The pressure loss predicted by the link below is 0.433psi per 100ft.
http://www.irrigationdirect.com/chart-pressure-loss-cast-iron-pipe
With QuickPipe, the index of such Cast Iron Pipe is 82 and we obtain 0.4106164psi per 100ft.

For 12” Cast Iron Pipe at 2000GPM, the link says the pressure loss would be 0.648psi/100ft. With QuickPipe, the index of such Cast Iron Pipe is 87 and we obtain 0.6002149psi/100ft. You can see the numbers agree with each other on both small and larger nominal sizes within marginal differences.

The third example is the pressure loss of 3/4” Galvanized Steel Pipe Sch40 at 3GPM. The pressure loss predicted by the link below is 1.11psi per 100ft.
http://www.engineeringtoolbox.com/pressure-loss-steel-pipes-d_307.html
With QuickPipe, the index of such Galvanized Steel Pipe Sch40 is 142 and we obtain 1.1448107psi per 100ft.

For 8” Galvanized Steel Pipe Sch40 at 2536GPM, the link says the pressure loss would be 4.6psi/100ft. With QuickPipe, the index of such Steel Pipe Sch40 is 153 and we obtain 4.447429psi/100ft. Before you see the resulting numbers, you may see an alert window popped up telling you that the fluid velocity is larger than 8ft/sec as shown in the figure below. This is another good example to show you that you will hardly deviate your design from the rules by using QuickPipe.
Anyway, you can see the numbers agree with each other on both small and larger nominal sizes within marginal differences.

For plastic pipes, here we pick PVC Sch40 pipe as the 4th example. The pressure loss of 1/2” PVC Pipe Sch40 at 2GPM predicted by the link below is 1.8psi per 100ft.
http://www.engineeringtoolbox.com/pvc-schedule-40-pipe-friction-loss-diagram-d_1147.html

With QuickPipe, the index of such PVC Sch40 pipe is 170 and we obtain 1.8127189psi per 100ft.

For 8” PVC Pipe Sch40 at 1000GPM, the link says the pressure loss would be 0.72psi/100ft. With QuickPipe, the index of such PVC Sch40 Pipe is 180 and we obtain 0.7147681psi/100ft. You can see the numbers agree with each other on both small and larger nominal sizes within marginal differences.

For hoses, we can still find a link to compare how QuickPipe predicts the pressure losses. The pressure loss of 1/2” hose at 2GPM predicted by the link below is around 5.0psi per 100ft.
http://www.engineeringtoolbox.com/pvc-schedule-40-pipe-friction-loss-diagram-d_1147.html

With QuickPipe, the index of such hose is 3 and we obtain 4.7149849psi per 100ft.

For 6” hose at 1000GPM, the link says the pressure loss would be 2.7psi/100ft. With QuickPipe, the index of such 6” hose is 14 and we obtain 2.609281psi/100ft. You can see the numbers agree with each other on both small and larger nominal sizes within marginal differences.

After we are confident with the pressure loss predicted for unit length of pipe/tubes/hoses. We can move on to the prediction of overall pressure loss including not only the pipe/tubes/hoses but also any numbers of 90° Ells, 45° Ells, side branch of Tee, straight run of tee, couplings, ball valves, gate valves, butterfly valves and check valves. To calculate the overall pressure loss, each of the added parts to the pipework will be considered as additional length of identical nominal size. All the imaginary additional lengths will be summed up and multiplied by the unit pressure loss per length. This way we obtain the overall pressure loss.
Different pressure loss prediction formula could have different value of equivalent length for the same fitting or valve. QuickPipe is based on the values proposed by “The Copper Tube Handbook” published by Copper Development Association. However, as you can see the bottom first page of QuickPipe is “P Loss Setting” which provides an easy way for the users to change the values of equivalent length for fitting and valves at various nominal sizes. Please be noted that the current values are for flanged fittings and valves. For threaded fittings and valves, please double the values from the page of “P Loss Setting”. The users are also encouraged to change the values here based on his/her experience for more agreeable overall pressure loss prediction. For those without much practical experience on the overall pressure loss, we still suggest using the default settings for calculation.
On the page of “Overall Pressure Loss”, please simply input the values of Tube/Pipe/Hose length itself, and the quantities of 90° Ells, 45° Ells, side branch of Tee, straight run of tee, couplings, ball valves, gate valves, butterfly valves and check valves. QuickPipe will calculate the overall pressure loss for you based on the pressure loss per ft obtained in the previous page and overall pressure loss expressed as equivalent length of tube/pipe. Again, the units of pressure loss and length are changeable and please perform the unit changeover on the page of “Unit Setting” .

Why QuickPipe and who should use QuickPipe?

Search Keywords: “QuickPipe“, “Pipe Design“, “Pressure Loss“  on iPhone App Store

QuickPipe is an easy-to-use app which can assist engineers in designing fluid systems of incompressible flows.
It can help evaluate the heat transfer in the closed system or in pipes with running fluid. It can also help determine the pipe sizing based on the calculation of resulting overall pressure loss from the length of pipes and the numbers of 90° Ells, 45° Ells, side branch of Tee, straight run of tee, couplings, ball valves, gate valves, butterfly valves and check valves.

For engineers who are in the following industries, QuickPipe is the best tool to perform such complex calculations without even any laptops or desktops.
1.    Fluid cooling/heating
2.    Water handling
3.    Petroleum related
4.    Refrigeration
There is no more need to either record such formulas in your engineering calculators or manually tap to input by cumbersome keystrokes. You can easily tap in the required inputs and obtain the results you want with the iPhone/iPad/iPod at hand.


Both SI units and imperial units are included in the unit database and the changeover can be easily accomplished by the app itself.

QuickPipe Release Note (App Store)

Search Keywords: “QuickPipe“, “Pipe Design“, “Pressure Loss“
 
We are pleased to announce that a new iPhone App "QuickPipe" is now available for download from the iPhone App Store.

QuickPipe is dedicated for the calculation on fluid properties such as temperature, energy change, heat transfer, pressure loss and etc for pipes/tubes/hoses. The database consists of more than 50 different fluids, more than 200 different metal tubes/pipes and more than 200 different plastic pipes. With such database of wide coverage, QuickPipe can help engineers perform following calculations with ease.

1. Obtain the amount of heat transfer (aka energy change) based on temperature differences. (Alternative control parameters including both mass and volume of fluid.)

2. Obtain the heat transfer rate based on temperature differences. (Alternative control parameters including both mass and volume flow rates of fluid.)

3. Determine temperature differences from the amount of heat transfer in a closed system.
4. Determine temperature differences from the heat transfer rate in a dynamic system.
5. Check the nominal sizes, DN, outside diameter, internal roughness and weight per ft of various tubes/pipes.

6. Obtain the unit pressure loss of each pipe/tube/hose selected based from the values of the current flow rate and pipe/tube/hose length input by users.

7. Calculate the overall pressure loss based on the pipe/tube/hose length along with the numbers of 90° Ells, 45° Ells, side branch of Tee, straight run of tee, couplings, ball valves, gate valves, butterfly valves and check valves.

8. A complete unit database allows the user to select the most familiar units of energy, heatload, pressure, length, flow rates and etc.

9. An user-friendly interface to allow the change on the settings of the pressure Loss in Fittings and Valves expressed as equivalent length of tube/pipe/hose.
