A pump draws water from a 20 cm diam suction pipe and discharges through a 15 cm diam pipe in which the velocity is 3.60 m/s. The pressure is – 34. 465 kPa at A in the suction pipe. The 15 cm diam pipe discharges horizontally into air at C inclined at 45 degrees. Find the maximum height and range that the water can reach if B is 1.8 m. above A and 20 hp is delivered to the pump? Assume that the pump operates at 80 % efficiency and that the frictional loss in the pipe between A and C is 3 m

Question
A pump draws water from a 20 cm diam suction pipe and discharges through a 15 cm diam pipe in which the velocity is 3.60 m/s. The pressure is – 34. 465 kPa at A in the suction pipe. The 15 cm diam pipe discharges horizontally into air at C inclined at 45 degrees. Find the maximum height and range that the water can reach if B is 1.8 m. above A and 20 hp is delivered to the pump? Assume that the pump operates at 80 % efficiency and that the frictional loss in the pipe between A and C is 3 m.
Given:
h
Suction pipe
Discharge pipe
1.80 m
A
pump
Datum line
DA = 20 cm = 0.20 m
DB = Dc = 15 cm = 0.15 m
PA = - 34.465 KPa (suction pressure)
VB = Vc = 3.6 m/s
Pc = 0 (atmospheric pressure)
BHP = 20 hp
Pump efficiency = 80%
HLIA-C) = 3 m
