A 1:30 scale model of a cavitating overflow structure is to be tested in a vacuum tank wherein the pressure is maintained at 2.0 psia. The prototype liquid is water at 70°F. The barometric pressure on the prototype is 14.5 psia. If the liquid to be used in the model has a vapor pressure of 1.50 psia, what values of density, viscosity, and surface tension must it have for complete dynamic similarity between model and prototype?
