determining pressure drop when there are no know pressures after the valve

R Thread Starter remullis Dec 15, 2020 #2 Let me rephrase that. If I dont have a known P2 after a control valve, how do you go about calculating P2(drop).

P Philippe Trichet Dec 18, 2020 #3 If you know valve upstream pressure P1, valve travel, valve inherent characteristic, valve flow coefficient (Cv), flowrate, and medium specific gravity (assuming a liquid medium) you can get the theoretical value of P2.
