Yes, Gregcase, I refer to the heat generated by the implosion itself. Fluids of primary concern are water(tap & sea)and petroleum oils.

Can anyone offer leads or specific information regarding the observed temperature of cavitation implosions? My primary concerns are in the 20 thru 2,000 psi pressure range but any information will be helpful.

Hello fredb, You're right, of course. Ergo "and at a theoritical "0 psi" differential pressure." If, however, I wished to estimate flow under pressure I would calculate the total slip in gpm/psi based on the viscosity of the fluid. This brings up another point: Automatic2...

The information you seek should come from the pump manufacturer. If you are dealing with two external gears of equal size you can approximate the displacement in cubic inches per revolution by using the formula (OD-CD)*L*CD*pi where OD = Outside Diameter CD = Center Distance L =...

"Assuming" you are dealing with a positive displacement pump with unvarying clearances: you will experience a certain gpm/psi slip as defined by the manufacturer. This slip factor will be based on a given viscosity. The actual slip will vary as the viscosity varies: Say the given...
