FLUID MECHANICS


UNIT-I         BASIC CONCEPTS AND FLUID STATICS        

                                    

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

UNIT-II           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

UNIT-III          DIMENSIONAL AND MODEL ANALYSIS                                    

Need for dimensional analysis – Dimensional homogeneity -Methods of dimensional analysis – Similitude –types of similitude -Dimensionless parameters- application of dimensionless parameters – Model Analysis-Model laws- classification of models
