A 20 cm centrifugal pump delivers 13.2 lps at a head of 45 m when running at a speed of 1350 r.p.m. A similarly designed pump of 15 cm size runs at the same speed . What are the most likely values of discharge and delivery head serviced by this second pump ?

Q: m/N of oil flowing, calculate the power delivered Suction pipe is 1.4 N-m/N of oil flowing,…

A: Given:- 840 L/min crude oil sg=0.85 total energy loss=4.2N-m/N To find:- pressure at the pump level…

Q: a centrifugal pump discharges 300 gpm against a head of 55 ft when the speed is 1500 rpm. The…

A: Given Discharge= 300 gpm Speed= 1500 rpm Brake horsepower =6 Head = 55ft

Q: At Q = 2000 gpm: = head provided by pump 1 = 75 ft H2 = head provided by pump 2 = 125 ft ni =…
