Pump calculation question
Centrifugal pump pumps 3000L/min, 12 metres of head & 700RPM.
a) Find the new capacity & head required if the pump is running at 1200RPM
b) The power required at both speeds
Centrifugal pump pumps 3000L/min, 12 metres of head & 700RPM.
a) Find the new capacity & head required if the pump is running at 1200RPM
b) The power required at both speeds
I am assuming the impeller diameter is the same
Use the Pump Calculations on pg 31 of formulae and constanants to figure out a)
Q= l/min
n= rpm
h=head
D=1
for the b) part I would have to go back to my books to look at (typical 2nd class question)
Easier if you have the power given for 300 l/min pump
They absolutely won't give the power. Can't find part b in the book
