Individual Performance of Pumps in Parallel 1

[waterboy258]

Hi. How do i check performance, efficiency and mechanical condition of individual pumps running in parallel. I have the following information:
1. Total Flow
2. Total Discharge Pressure
3. Total Suction Pressure
4. Individual Discharge Pressure
5. Individual Suction Pressure
6. Total Power Consumption

Thank you.

With both units running together, you can't.

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.)

I'm assuming your interested in what happens when you turn one of the parallel pumps off?

Parallel pumps are discussed here:

2 more bits of info required: individual pump flow and liquid density.

Does 4 and 5 actually vary from 2 & 3?
