Basics: Definition of fluid, fluid properties such as viscosity, vapour pressure,
compressibility, surface tension, capillarity, Mach number etc, pressure at a point in the static
mass of fluid, variation of pressure, Pascal’s law, pressure measurement by simple and
differential manometers using manometric expression.
Unit 2
Fluid Static: Hydrostatic forces on the plane and curved surfaces, centre of pressure,
Buoyancy, centre of buoyancy, stability of floating bodies, metacentre and metacentric height
its application in shipping.
Unit 3
Fluid Kinematics: velocity of fluid particle, types of fluid flow, description of flow,
continuity equation, Coordinate free form, acceleration of fluid particle, rotational &
irrotational flow, Laplace’s equation in velocity potential and Poisson’s equation in stream
function, flow net.
Unit 4
Fluid Dynamics: Momentum equation, development of Euler’s equation, Introduction to
Navier-Stokes equation, Integration of Euler’s equation to obtain Bernoulli’s equation,
Bernoulli’s theorem , Application of Bernoulli’s theorem such as venture meter, orifice meter,
rectangular and triangular notch, pitot tube, orifices etc.
