Concept explainers

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.

Question

The water needs of a small farm are to be met by pumping water from a well that can supply water continuously at a rate of 50 L/min. The water level in the well is 13 m below the ground level, and water is to be pumped to the farm by a 2-cm internal diameter pipe. The required length of piping is measured to be 20 m, and the total head loss in the piping system is estimated to be 10 m.a) Using Bernoulli equation, determine the pressure difference between the two points (A & B).
