Basic Fluid Mechanics and Hydraulic Machines

Fluid mechanics is concerned with the behaviour of liquids and gases at rest and in motion
The proper understanding of mechanics of fluids is important in many branches of engineering:
in biomechanics the flow of blood is of interest; ocean currents require a knowledge of fluid
mechanics; chemical processing of plants require a thorough knowledge of fluid mechanics;
aeronautical engineers require knowledge of flow of air over the aircraft to reduce drag and
increase lift; mechanical engineers require knowledge of fluid propel1ies to design pumps,
water turbines, gas turbines and rockets; civil engineers require fluid mechanics to study
river currents and erosion; and environmentalists require knowledge of fluid properties for
solving pollution problems of air and water to control flood, irrigation channels, etc.
