The experiment explores the critical flow properties of two phase
steam in a well rounded converging orifice. Mass flow rates were obtained
over a quality range of 0.34 to slight superheat at pressures of 20 to 60
psia. Attempts were made to correlate previously determined velocities of
wet steam with mass flow rates in order to evaluate the liquid-vapor
velocity ratio, or slip ratio. It became apparent, however, that limitations
imposed by the orifice size yielded nonuniform values of the slip
ratio across the orifice.
