INLET AND EXIT LOSSES FOR PUMP
INLET AND EXIT LOSSES FOR PUMP
(OP)
Hi guys,
I need to find the inlet head losses and exit head losses for a pump rated at 140m3/hr at 62m. Can you please provide the formula for obtaining these losses.
* the inlet size is 4"
* the exit size is 3"

These losses are negligible.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

Nope its not related to my other posts. I am developing a system resistance curve for a new pumping system project at our tank farm. I needed to factor in the losses at the entrance of the pump and the exit of the pump. I was hoping I could get the formulae.
RE: INLET AND EXIT LOSSES FOR PUMP
If you mean the piping, then there are many equivalent length formulae about for reducers, elbows etc. For a system resistance curve that's what you need to know.
