• A Textbook of Fluid Mechanics and Hydraulic Machines
by R.K. Bansal

OBJECTIVE
• To understand the structure and the properties of the fluid.
• To understand and appreciate the complexities involved in solving the fluid flow problems.
• To understand the mathematical techniques already in vogue and apply them to the solutions of practical flow problems.
• To understand the energy exchange process in fluid mechanics handling incompressible fluids.

BASIC CONCEPTS AND PROPERTIES
Fluid – definition, distinction between solid and fluid – Units and dimensions – Properties of fluids – density, specific weight, specific volume, specific gravity, temperature, viscosity, compressibility, vapour pressure, capillary and surface tension – Fluid statics: concept of fluid static pressure, absolute and gauge pressures – pressure measurements by manometers and pressure gauges.

FLIUD KINEMATICS AND FLUID DYNAMICS
Fluid Kinematics – Flow visualization – lines of flow – types of flow – velocity field and acceleration – continuity equation (one and three dimensional differential forms)- Equation of streamline – stream function – velocity potential function – circulation – flow net – fluid dynamics – equations of motion – Euler’s equation along a streamline – Bernoulli’s equation – applications – Venturi meter, Orifice meter, Pitot tube – dimensional analysis – Buckingham’s  theorem- applications – similarity laws and models.

INCOMPRESSIBLE FLUID FLOW
