A pump draws water from a reservoir A (EL 0m) and lifts it to reservoir B (EL. 80m), the headloss are: From A to point 1=3(?1²/2?) and From point 2 to B= 20 (?2²/2?). Point 1 is before pump and Point 2 is after pump. Point 1 and Point 2 are lying on the same elevation, which is 6m below reservoir A. The pipe connecting reservoir A to pump is 15cm while the pipe connecting pump to reservoir B is 10 cm. If the system flow is 15Lps compute for the following. A)Power output in BTU/min B)Pressure head at point 2 in m C)Power input in lb-ft/s if the pump efficiency is 78%

Question
A pump draws water from a reservoir A (EL 0m) and lifts it to reservoir B (EL. 80m), the headloss are: From A to point 1=3(?1²/2?) and From point 2 to B= 20 (?2²/2?). Point 1 is before pump and Point 2 is after pump. Point 1 and Point 2 are lying on the same elevation, which is 6m below reservoir A. The pipe connecting reservoir A to pump is 15cm while the pipe connecting pump to reservoir B is 10 cm. If the system flow is 15Lps compute for the following.
A)Power output in BTU/min
B)Pressure head at point 2 in m
C)Power input in lb-ft/s if the pump efficiency is 78%
