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.
