Problem 1 consists of ten questions to be solved consecutively. The objective is to pump 280 gal/min of water at 60 °F from underground reservoir. The suction pipe is 32 in Sch.40 steel pipe and its total length is 13 feet with 90° standard elbow. The pressure drop across the suction line must not be greater than 5 psig. It is desired to add a foot valve hinged disc at the inlet of the suction line. Would you approve that? 不 -2P 5 ft Datum- Foot Valve hinged disc

Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.
