Thanks for your reply but please explain regarding the formulas below.
Total Disch Head = hsd + hfd + hvd ± hpd
Where:
hsd = Discharge Static Head
hfd = Discharge Friction Head
hvd = Discharge Velocity Head
hpd = Discharge Pressure Head
Total Suction Head = hss – hfs + hvs ± hps
Where:
hss =...
Hi everyone. I wanna ask regarding friction head, why is it at total discharge head calculation the friction head is added while in total suction head calculation the friction head is subtracted?
Is it a right choice to select Plan 11 + Plan 53b flush plan for condensate process fluid without any caustic mixture? or do I have to select Plan 11 only.
