Scratch that last post.
I've already answered my own question. The discharge pressure will be equal to system back pressure (1450kPag) plus any frictional loss + pressure head in the temporary hose which in this case equals 1450kPag + 50kPag = 1500kPa. That means the PSV is well high enough...
Thanks for the reply LittleInch. I think you've uncovered my confusion which I appreciate.
What will the pump discharge pressure be in this instance? See attached the flow curve for the pump.
Certainly with you on the "temporary" rant BUT I suspect this customer will make sure it stays temporary.
Folks,
I've been asked to check the PSV sizing for a temporary chemical injection skid our company has proposed. It's been a while since I've looked at pump sizing and there is one thing bothering me.
The setup is a Checkpoint 1500, 1" plunger pump injecting 25L/h into a system operating at...
