A method is presented for estimating the mass flow rate-pressure drop characteristics of compressible gas-liquid mixtures flowing through pipeline restrictions. The method can be applied for all two-phase Mach numbers with values of Ma(tp) less than or equal to one. Predictions of the method are compared with a number of experimental data sets for air-water flows through nozzles and air-water and air-oil flows through orifice plates. The agreement is typically within +/-8% for nozzles and within +/-12% for orifice plates. The application of the method to flow through rupture discs and pressure relief valves is discussed.
