A pump delivering 230 lps of water whose absolute viscosity is 0.0114 Poise has a 300-mm diameter suction pipe and a 254-mm diameter discharge pipe as shown in the figure below. The suction pipe is 3.5 m long and the discharge pipe is 23 m long. The water is delivered 16 m above the intake water level. Considering the head losses in fittings and valves, find the head which the pump must supply. If the motor brake power of the driving motor is 75 kW, what is the efficiency of the pump? Assume the pipe material as cast iron. Given: A figure showing a pumping installation Q = 230 Ips BP = 75 kW D. = 300 mm D. = 254 mm u = 0.0114 Poise = 0.00114 Pa-s. compute for the friction factor using the coolebrook equation

Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.
