Pipe Flow Calculations Forum

You can use pressure drop calculator and choose to calculate flow rate.

You can try with thermal energy calculator . Here are results that I have with your inputs: Heater/Chiler calculator 1. mass flow rate (w): w : 1.1944578 kg/s 2. volumetric flow rate (q): q : 4.3000445 m3/h 3. density (ρ): ρ : 1000.0 kg/m3 4. diameter (D): D : 60 mm 5. velocity (V): V : 0.422453 m/s...

If K is changing also expansion Y is changing. If you have higher local resistance and K is higher, fluid will expand more.

Power of pump can be calculated as P = Q * (p1 - p2). Pressure drop is due to friction, local resistances and change in elevation between start and end of pipe. So, if you calculate pressure drop in pipe (p1 - p2) for some flow rate, you can also calculate power of pump for that flow rate. And that ...

What do you mean by pipe taps?
You have corner taps as selection also - if plate is between flanges and taps are on flanges itself.

Flow rate through pipe is established based on the energy (mainly pressure) difference from start to the end of pipe. If you have bigger pressure difference flow rate will be higher. If you have same pressure difference flow will be higher when resistances are lower. When you have the end of pipe un...

You can use calculator for change in elevation, but you have to enter that like pressure difference - like elevation difference of 10 m with water in pipe is pressure difference of 10 mWS. Flow regime is laminar or turbulent depending on the flow itself. You do not need to worry about it. Calculator...

Here is what I have with pressure drop calculator just for sudden expansion: 1. volume flow rate (q): q : 0.75 m3/s 3. pipe length (L): L : 1 mm 4. pipe diameter (D): D : 120 mm 5. pipe roughness (kr): kr : 0.1 mm 6. density (ρ): ρ : 1.293 kg/m3 7. kinematic viscosity (ν): ν : 17.3 mm2/s 8. dynamic ...

I am not sure that I understand you correctly. You have 100 m long gas pipe line 4" and 4" governor before the burner? The governor has 1.2 bar inlet pressure when burner is off? The governor lets 400 mbar with burner off? When burner starts, pressure goes down to 200 mbar after the governor and 700...

You can't have two flow rates in one pipe with incompressible fluid like water, so with pump flow dropping from 50 to 40, pipe flow rate will change as well with speed of sound from point a to point b.
