Compressor Settleout iteration
Compressor Settleout iteration
(OP)
Looking at determining system pressure after failure of isolation of discharge pressure to suction piping(lower pressure rating). The calculation requires finding the final pressure.
T final= H/(Cp*Total mass) - at settleout with combined suction and discharge masses and volumes
P final = (Total mass/MW * R * T *z)/V
The iteration requires assuming Z and Cp and solving for T. My question is what is the back check for the iteration? I think you use the Pressure result to then check against the assumed Cp. Or is P and T used to check against asssumed Z, or both?
