Calculation of compressed air flowrate
(OP)
I need to find out the flowrate of compressed air for air nozzle. Anyone knows the formula to calculate the flowrate?

Calculation of compressed air flowrate

RE: Calculation of compressed air flowrate
mass flow rate = P*A*M*(gamma/(R*T))^0.5
where
P is static pressure
A is area
M is mach number
gamma is ratio of specific heats (1.4 for air)
R is gas constant
T is static temperature
Make sure you use consistent units and make sure that P, A, M, and T are values from the same cross section of the flow.
If your flow is choked, the formula can be simplified.
