Basic Fluid Mechanics and Hydraulic Machines
.jpg)
Fluid mechanics is concerned with the behaviour ofliquids 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 offluid
mechanics; chemical processing of plants require a thorough knowledge offluid mechanics;
aeronautical engineers require knowledge offlow 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 offluid properties for
solving pollution problems of air and water to control flood, irrigation channels, etc.
There are special ised books on fluid mechanics for each of these areas and therefore
this book will present only general properties of
fluid flow
