Establishing a new method for determining valve flow coefficient
on the critical pressure ratio of an ideal nozzle: For an "ideal nozzle," the maximum flow for a given inlet pressure always occurs when sonic velocity is reached at the throat, where the outlet absolute pressure is 0.528 times the inlet absolute pressure. This is correct for all well-radiused orifices...
