WebEquations are developed for the pressure drop over sharp-edged orifices during the flow of incompressible two-phase mixtures. The velocity ratio is assumed constant during flow through the orifice, and on this basis analysis of the data leads to the following equations for the velocity ratio: for X ≥ 1, K = (p L /p HOM) 1/2 for X ≤ 1, K = (p L /p G) 1/4.
