QUESTION 2 (20 marks) A pump transports a chemical solution at a flowrate of 250 L/s from an underground tank at 20 kPa to a reactor at 40 kPa as shown in Figure 2. The specific gravity and dynamic viscosity of the chemical solution is 1.1 and 3.2 x 103 Ns/m2 respectively. The 75 mm diameter suction pipe is 8 m long and has one fully opened globe valve. The 50 mm diameter discharge pipe is 60 m long and consists of one swing check valve, five standard 90 elbows and two ball valves. All valves are in fully opened position. Material of both suction pipes and the discharge pipe are stainless steel. Density of water is 1000 kg/m3. 40 kPa al Discharge piping 6 m Reactor 3 m 20 kPa Suction piping Underground tank 3 m Figure 2 Calculate the: (a) frictional head losses in the suction and discharge pipes; (8 marks) (b) localised head losses in the suction and discharge pipes: (6 marks) (c) pump head required by the system; and (4 marks) (d) hydraulic power of the pump.
