Calculating flow rate

  1. Aug 17, 2010 #1
    I need to hook up an instrument that requires a source of compressed air at 47psi and 4cfm. I have a pressure gauge so I can measure the pressure at the source. It seems to me that I should be able to calculate the flow rate if I know the pressure and the diameter of the pipe. Can anyone help me figure that out?
