Pump expected flow from curve
Pump expected flow from curve
(OP)
Hi All
I have a centrifugal pump that I am not certain what the flow is that I am getting out of it. The pump sucks from a tank 1m above it that is open to atmosphere. I have measured the shutoff head at 600kPa. The impeller size is 417mm. How do I go about doing this?
Thanks in advance.

Alternatively measure the discharge pressure while pumping and sees where that intersects with the pump curve. Your 1m inlet head is 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.)

This is a very efficient pump though - I haven't seen many with efficiency over 80% never mind 86 at the BEP.

And this is a pump in operation since 1992...not bad!
