Properties of Fluids & Dimensional Analysis. a) Definition of fluid and fluid mechanics: examples and practical applications involving fluids at rest and in motion, physical properties of fluids: density, specific weight, specific volume, relative density and viscosity. Newton’s law of viscosity, classification of fluids, rheological diagram, Dynamic and kinematic viscosity, compressibility, cohesion, adhesion, surface tension, capillarity, vapour pressure, problems involving use of above fluid properties. b) Dimensions of physical quantities, dimensional homogeneity, dimensional analysis using Buckingham’s π theorem method, geometric kinematic and dynamic similarity, important dimensionless parameters, Reynold’s No., Froude No. and their significance. Fluid Statics, Buoyancy a) The basic equation of hydrostatics, concept of pressure head, measurement of pressure (absolute, gauge), application of the basic equation of hydrostatics, simple manometers, diff...
