Question
A 60% efficient pump delivers water at 20°C from one reservoir to another one 15 m higher, as seen
in the figure below. The system consists of 24 m of galvanized steel 7-cm ID pipe (ε = 0.150 mm), a
suction pipe entrance, two 90° long-radius elbows and a 6° conical exit. What is the required input
power to the pump (in W) needed if the flow rate is 60.0 m³/hour? (8 pts)
Useful data: L/Dsuction pipe entrance = 90, L/D90° long radius elbows = 35; L/D6° conical exit = 20
