In a soya bean oil manufacturing plant, soya bean slurry at 20C is pumped from a collection tank to a cooler operating at 50 kPa and located 3.5 m above the tank. From the tank, the slurry flows at the rate of 1.5L/s through a total of 5.6m of 2.54 cm ID stainless steel commercial pipe, three 90 elbows (standard), a straight tee (used as coupling for mounting pressure gauge) and a gate valve (open). Assuming the pump has an efficiency of 78%, estimate the power requirement in hp of the pump. The density for soybean slurry is 1041 Kg/m3 while the viscosity is 4.53 x 10-3 Pa-s. Conversion: 1hp = 0.7457 kW Answer: 0.103 hp

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.
