Thank you. I assumed it was proportional to the flow rate. However I wasn't sure if it was linear or quadratic. It seems I'll have to use a more mathematical approach using proportion instead of recalculating the friction factors etc.
This equation seems to be backwards. Wouldn't it be P = C Q^2?
So assuming laminar flow. fD=64/Re does not seem to relate pressure to flow rate in any case. How would I incorporate pressure and flow rate into that equation?
The issue is that I don't know any pipe details atm so I can't put in L, d etc. I need to have a mass balance so I can use ratios to define a proportional relationship.
Thanks for the reply. I forgot to mention the application is water. Furthermore the pipe is the same so some factors should be canceled out.
Furthermore this equation does not seem to relate Pressure to Flowrate. Only Flow rate to head loss. Am I to assume that 400kpa is effectively 40m head...
Hi,
I can't go out and measure this system up atm. But I have 36m^3/s flow rate at 400kpa. How would I go about predicting the flow rate at 500, 600, 700 and 800 kpa through the same pipe? I think it's a linear relationship but want to be sure. Thanks.
