Answer:
As per the affinity law:-
So we say that if we increase RPM of centrifugal pump then flowrate , head and power will increase.
2. If we increase the RPM of a centrifugal pump then NPSHr will increase
So if you increase RPM with other specifications remain same then chances of cavitation.
I hope you got your answer.
