Pipe Flow Calculations Forum

Have you tried with orifice plate calculator?

Here is how you can calculate pipe diameter . Also, you can use pipe diameter calculator . From calculator you will have velocity also. Here is how you can calculate friction coefficient for pipe line. Static pressure of 0.962 m and 40lb/ft3 fluid is p=rho*g*h=640.6 kg/m3 * 9.81 * 0.962 m = 6045 Pa ...

Pressure p2 is the pressure on the tank that is 2100 ft away - if I understand you correctly it is tank open to atmosphere, so it is atmosphere pressure in ftWS. Also p1 is absolute pressure. Once you know flow rate you should be able by changing diameter to calculate required pump head and so you w...

What is the flow rate you want to have? You should use pressure drop calculator , and that 100 ft elevation should be added to calculated pressure drop with calculator. See attached image assuming flow of 20 gpm. Calculated pressure drop is 19.5 ftWS - feets of water, so for 20 gpm you will need pum...

On every calculator you can find theory button which will open web page with theory and equation used. To have laminar conditions Re number must be lower that 2320, so using Re number calculator you can check the velocity. Here is Report to Q1: Reynolds number calculator 1. diameter (D): D : 2 in 2....

do you have Java?
You should see blue "click here to start calculator".

You can use control valve calculator

You can use natural gas calculation theory

You can use this one

Can you tell me required flow rate?
