centrifugal pump Flashcards
1
Q
objective
A
determine performance characteristics of a Bell and Gossett Model 1510 centrifugal pump and compare to manufacturer’s test data
2
Q
objective goals
A
obtain performance curves for pump head, power input to pump, and pump efficiency as a function of flowrate for different speeds
3
Q
conservation of energy
A
pump head = (pressure diff / specific weight) + (discharge velocity squared - suction velocity squared)/2g
4
Q
power delivered to water by pump
A
work out = specific weight of fluid * flowrate * pump head
5
Q
power delivered to pump by motor
A
work in = angular velocity * torque
6
Q
pump efficiency
A
efficiency = work out / work in
