Q1: A pipeline joining a lake and a reservoir whose water levels differ by 91.4 m has a diameter of 45.7 cm and a length
of 6100 m and the friction factor f is 0.008. The gravity flow is inadequate and it's necessary to install a pump halfway
along the pipeline to act as a booster. The pump equation is H = 183 – 760 Q? + 32.5 Q where H is the head
developed by the pump in meter and Q the flow in m'/s .Estimate
c) The percentage increase in the flow rate due to the pump.
d) The daily operating cost of the pump, if the overall efficiency
hour (kWh).
70%, and the cost of power is 0.02 $ per kilowatt-
Q2: Tests on a single centrifugal pump running at 600 rev/min gave the results indicated below Calculate:
1- The speed of the pump and input power will be required to deliver 2.72 m of water per minute continuously
against a head (including friction) of 15.2 m.
2- The number of pump connected in series to rise the water to 42 m.
3- The number of pump connected in parallel to deliver a 0.28 m/s.
