Fluid and their properties : Concept of fluid, difference between solids, liquids and gases;
ideal and real fluids; Continuum concept of fluid: density, specific weight and relative density;
viscosity and its dependence on temperature; surface tension and capillarity, vapor pressure and
cavitation, compressibility band bulk modulus; Newtonian and non-Newtonian fluids.
Fluid Statics : Concept of pressure, Pascal’s law and its engineering hydrostatic paradox.
Action of fluid pressure on plane (horizontal, vertical and inclined) submerged surface, resultant
force and center of pressure , force on a curved surface due to hydrostatic pressure. Buoyancy
and flotation, stability of floating and submerged bodies, Meta centric height and its
determination.
Fluid Kinematics: Classification of fluid flows, velocity and acceleration of fluid particle, local
and convective acceleration, normal & tangential acceleration streamline, pathline and
streakline, flow rate and discharge mean velocity continuity equation in Cartesian co-ordinates.
Rotational flows- Rotational velocity and circulation, stream & velocity potential functions.
Fluid Dynamics :- Euler’s equation, Bernoulli’s equation and steady flow energy
equation;representation of energy changes in fluid system, impulse momentum equation, kinetic
energy and momentum correction factors, flow along a curved streamline, free and forced vortex
motions.
Dimensional Analysis and Similitude: Fundamental and derived units and dimensions,
dimensional homogeneity, Rayleigh’s and Buckingham’s Pi method for dimensional analysis,
dimension less number and their significance, geometric, kinematic and dynamic similarity,
model studies.
Flow Past immersed bodies: Drag and lift deformation Drag and pressure drag. Drag on a
sphere,cylinder and Airfoil: lift-Magnus Effect and circulation, lift on a circular cylinder.
Flow Measurement:- Manometers, Pitot tubes, venturimeter and orifice meters, orifices, mouth
pieces, notches ( Rectangular and V-notches) and weirs ( Sharp crested Weirs).
