A portion of a fire protection system in which a pump draws water from a reservoir at the rate of 0.145 m/s is shown on figure 5. The diameter of the 8-inch schedule 40 line is 202.7 mm. All values of friction factor in the zone of complete turbulence, fr is 0.026. The value of friction factor in the suction and discharge steel pipes, f is 0.023. The globe valve is fully open and has L/D = 340, the check valve (ball) after the pump has L/D = 150, the gate valve has L/D = 12 and the elbow is standard with L/D= 30. The entrance is square edged, hu = K v2/2g and K = 0.5. Consider all losses in both the 22 m suction line and the 250 m discharge line. If the pressure at B on the discharge is to be 45 kPa, calculate: a) the total losses, hl [12 marks] b) the head added by the pump, ha [5 marks] c) the power added to the fluid [1 mark] d) the power required by the pump [2 marks] Gate_Valve Vent 250m long B 8-in Schedule 40 steel pipe from pump Flow 12m Check Valve 22m 8-in Schedule 40 5m Steel pipe) Reservoir Pump Globe Valve Figure 5
