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. To what height h above B can the water be raised 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.Determine the inclination angle at point C for the water stream to reach a range of 10 m. Also calculate the maximum height that the water can go from the selected datum plane.
