Pipe Flow Calculations Forum

Here is calculator that you can use for air flow calculation

Hope attached image will be of help on use of calculator.

You must tell pressure on the start and pressure on the end of also. Also you must know hose length.
You can use air pressure drop calculator.

You can use air flow calculator

You can find also K - resistance factor calculator there

If you have higher pressure, flow will be higher. If you have bigger diameter flow will be higher. If the pipe length is longer flow will be lower. What is the length of the pipe or is it just orifice?
What is the fluid?

If the tank is open to atmosphere your p1=0.
But as you do not have option to enter height in calculator, you can enter 50 + 800 mWS as p1. p2 = 0.
Also you have K1 = 0.5 (pipe entrance) and K2 = 1 (pipe exit) with total of K1 + K2 = 1.5 total resistance coefficient.

Hope this helps!

You can try with gas flow calculator

Here is air flow calculator that can help you.

I am sorry to hear that you can not access calculators. It works fine on my side. I am using 1.6.0_29.

flow with 60psi coming in from the street Height difference between point where you know pressure and sprinkler is needed. Here is the report for your problem using Pressure drop and flow rate calculator 1. volume flow rate (q): q : 1.55 ft3/s 2. weight flow rate (w): w : 158007.61 kg/h 3. pipe len...
