1. The piston of a double-acting simplex piston pump is 150 mm in diameter and has a of 450 mm. The suction and discharge pipes have a diameter and length of 100 mm, 6 m and 75 mn, 60 m respectively. The suction is 45 m below and the discharge is 45 m above the pump. If the pump runs at 60 rpm, determine the power required if the efficiency is 85% Assam a friction factor of 0.02 and simple harmonic motion. 2 A pump transports water from a large, open source to an open tank. The discharge tuhegem is 21 m long and 100 mm in diameter, the friction factor being 0.020 bottom of the tank is 10 min above the free surface of the source and the water in the tank has sama depth of 1.5 m. The pump operates at 1750 rpm and its characteristic curves at this speed are represented in the table below. Q (Us) H (m) (%) 6.0 16.0 30 12.0 16.5 55 18.0 15.5 70 24.0 14.5 76 30.0 13.5 70 36.0 10.5 57 42.0 7.0 38 2) Determine the operating point and power required to operate the pump. b) Determine the speed of rotation if the flow rate increases to 34.0 L. c) A valve is installed at the discharge to limit the volumetric flow to 24.0 L/s when the pump operates at 1750 rpm, determine: (1) The power consumed by the pump: (ii) The power dissipated in the pump; (iii) The power dissipated by friction in rubbing: (iv) The power dissipated in the control valve, (3) The overall performance of the installation 3 A superphosphate fertilizer is transported to an open storage silo by a pneumatic system. The production rate is 10 ton/h of product, with an average particle size of 200 uum and a density of 150 ib/ft. The conveyor unloads at a point 70 ft above the outlet location 500t away from it, Calculate the tube diameter, the volumetric flow rate of ur and the pressure at the inlet of the tube so that the product is satisfactorily conveyed when the fan is located at the load end of the system Good job
