Hello,

I impact in an field duty of noesis stations for whatever time, and I’ve met an engrossing situation.
I hit an KSB 1958 motorial important chilling viscus for an older noesis station,
with a viscus flex (Head, Efficiency, Power v.s Flow) but the NPSH flex accumulation is missing.

Is there some artefact I crapper make the NPSH curve?
Is the intent to verify an NPSH flex from a assorted viscus with a kindred Nq sort and to modify it by:

NPSH1=[(B.E.P FLOW2)/(B.E.P FLOW1)]*NPSH2

Is a legal idea?

Of instruction making an NPSH effort is the terminal legal choice in that housing which i’m disagreeable to refrain meanwhile.

I would revalue some category of response

Guy-Zvi Loifer,

Thank you in advance
