WebIn this lab, compressible gas flow through a piping system consisting of a critical flow nozzle, pressure gauges, flow meters, orifices, and a tank was observed. ... discharge … WebThe flow coefficient, which describes the flow capacity of a valve, is an empirically determined constant equal to the valve's flow capacity in U.S. gallons per minute of water at 60 °F when a pressure drop of 1 psi exists across the valve in its most wide-open position. Table 1 lists C v for all sizes of DANTROL-270 valves, with and without trim.
