    Choking in a Circular Orifice Plate in a pipe

    The equation I have for velocity through a circular orifice plater is as follows: Ud = \frac{Yi\timesC}{\sqrt{(1-(d/D)^4)}}\sqrt{\frac{(2\times(P_{2}-P_{1})}{\rho}} To my understanding, flow becomes choked when this velocity exceeds a Mach number of 1, and is no longer sub-sonic...
