F = x D2 x P Where: F = Flow in scfm D = The equivalent hole diameter P = Pressure in psig It is assumed that the flow coefficient is, temperature is 120°F and gas is air. For example: If a 1/ 8" choke is installed in a hammer then the additional air required to operate the hammer at 350 psi would be: F = x x 350 F = 53 ...
