Hi, I'm tryin to calculate pressure drop across a valve when the fluid state is transcritical. On discharge side (before gas cooler) and on gas cooler return. Valve KV value is known. P1, P2 and massflow are known. I can find the formula for both superheated vapor and saturated liquid, but didn't find anything for transcritical state. thank you,
