Piping Pressure Drop Calculation Software

Piping Pressure Drop Calculation Software

Piping Pressure Drop Calculation Software

(OP)
Looking for a pipe pressure drop software package (or spread sheet) that calculates pipe & fitting losses with head/100ft & fitting velocity effects built in.

RE: Piping Pressure Drop Calculation Software

I think Elite makes something:  http://www.elitesoft.com/
I also found an old diskette (DOS 3.1?) labelled pressure drop calcs,  probably from a vendor.  If you're interested, email me, and I'll shoot you the file, no guarantees!

RE: Piping Pressure Drop Calculation Software

We utilize a software called PipeFlo Professional that allows you to create your own piping system including pumps, valves, regulators, pipe material, various fluids, etc.  The website is http://www.eng-software.com  ;

RE: Piping Pressure Drop Calculation Software

If you are looking for single pipe pressure drops, try this link to McQuay's website.

Download the Pipesizer program and install it.  This site also has Psychrometrics and Duct Sizing software available.

RE: Piping Pressure Drop Calculation Software

Trane Pipe Designer has the ability to do this. The program is also pretty inexpensive.

RE: Piping Pressure Drop Calculation Software

Try to make a spreadsheet for it. For water a good enough approximation for head loss in ft of water is:

h = 0.001599 x L x (100/C)^1.85 x ((GPM)^1.9046)/((d)^1.9921)

where h = ft of water
L = equivalent length of piping including equivalent length for loss through fittings

C = Hazen & Williams Friction factor which varies for type of pipe material & age. Design value is 100 for new steel pipe.
d = inches inside diameter of pipe

For design increase head loss by minimum 15% to allow for aging for closed systems. For open systems increase by minimum 26%.

I derived the equation to get a close match to Cameron Hydraulic Data  tables.

See it also for recommended equivalent length factors for various fittings.


RE: Piping Pressure Drop Calculation Software

Correction:
Use 40% to 75% more loss for open systems and minimum 15% more for closed systems. The 75% being for piping 30 years old. Apply the aging factors only to the actual run of piping, not to the equivalent length portion of fittings.
