Q4. (a) List out the major losses and minor losses in a pipe flow. (b) A pump delivers water from a tank A (water surface elevation= 110 m) to tank B ( water surface elevation = 170 m ). The suction pipe is 45 m long ( f = 0.024) and 35 cm in diameter. The delivery pipe is 950 m long ( f = 0.022 ) and 25 cm diameter. The head - discharge relationship for the pump is given by Hp = ( 90 ā 8000Q" ), where Hp is in meters and Q is in m3/s. Calculate: (i) The discharge in the pipeline. (10 marks) (ii) The power developed by the pump. (10 marks)

In this case, the major losses would be the friction losses in the suction pipe and the delivery pipe. Minor losses in a pipe flow are generally due to changes in the direction of flow, obstructions in the flow, sudden or gradual changes in the cross-sectional Show moreā¦

Water from an open reservoir A at 8 m elevation is drawn by a motor-driven pump to an open reservoir B at 70 m elevation. The inside diameter of the suction pipe is 200 mm and 150 mm for the discharge pipe. The suction line has a loss of head three times that of the velocity head in the 200 mm pipe. The discharge line has a loss of head 20 times that of the velocity head in the discharge pipeline. The pump centerline is 4 m. The overall efficiency of the system is 78%. For a discharge rate of 10 li/s, find the power input to the motor.

Water is pumped at the rate of 0.075 m3/s from a reservoir 20 m above a pump to a free discharge 35 m above the pump. The pressure on the intake side of the pump is 150 kPa and the pressure on the discharge side is 450 kPa. All pipes are commercial steel of 15 cm diameter. Determine (a) the head supplied by the pump and (b) the total head loss between the pump and point of free discharge.

A sump pump (used to drain water from the basement of houses built below the water table) is draining a flooded basement at the rate of 0.750 L/s, with an output pressure of $3.00 \times 10^{5} \mathrm{N} / \mathrm{m}^{2} .$ (a) The water enters a hose with a 3.00-cm inside diameter and rises 2.50 m above the pump. What is its pressure at this point? (b) The hose goes over the foundation wall, losing 0.500 m in height, and widens to 4.00 cm in diameter. What is the pressure now? You may neglect frictional losses in both parts of the problem.
