Hi Everyone
I have been calculating a PSV for a blocked outlet relief scenario (discharge of a oil pump.) and sizing the discharge line, the results show that i should use a 8" diameter line, but I can't use that diameter because of the intallations and i tried with 6" and the mach number result is 0.77. I was wondering what are the effects of having high mach number in a liquid relieving that will connect to the suction of the pump?, the length is not more than 4 meters.
