Introduction Dimensions and Units The physical characteristics of liquids – Specific gravity viscosity and vapour pressure, their influence on fluid movement and stress at a point, Pascal’s Law, Hydrostatic law atmospheric gauge pressures and vacuum pressures- measurements of pressure. Pressure gauges Manometers Differential as well as Micro Manometers.
Hydrostatics Forces of hydrostatic force on submerged planes, horizontal vertical, inclined, and curved surfaces – the centre of pressure.
Fluid Kinematics Description of the fluid flow, streamlines, paths, streak stream tube and line. They classify as steady, irregular, unsteady, non-uniform turbulent, laminar Irrotational and rotational flows Equation of continuity for one, two, and three-dimensional flows including velocity and stream functions Analysis of flow nets.
Fluid Dynamics Body and surface forces the equations of Bernoulli and Euler to describe flow along a line of stream Momentum equation and its application to move on bends of pipe.
