**UNIT 1:**

Review of Fluid Properties: Engineering units of measurement, mass, density, specific weight,
specific volume, specific gravity, surface tension, capillarity, viscosity, bulk modulus of
elasticity, pressure and vapor pressure. Fluid Static’s : Pressure at a point, pressure variation in
static fluid, Absolute and gauge pressure, manometers, Forces on plane and curved surfaces
(Problems on gravity dams and Tainter gates); buoyant force, Stability of floating and submerged
bodies, Relative equilibrium.

**UNIT 2**:

Kinematics of Flow : Types of flow-ideal & real , steady & unsteady, uniform & non uniform,
one, two and three dimensional flow, path lines, strea klines, streamlines and stream tubes;
continuity equation for one and three dimensional flow, rotational & irrotational flow,
circulation, stagnation point, separation of flow, sources & sinks, velocity potential, stream
function, flow nets- their utility & method of drawing flow nets.

**UNIT 3**:

Dynamics of Flow: Euler’s equation of motion along a streamline and derivation of Bernoulli’s
equation, application of Bernoulli’s equation, energy correction factor, linear momentum
equation for steady flow; momentum correction factor. The moment of momentum equation,
forces on fixed and moving vanes and other applications. Fluid Measurements: Velocity
measurement (Pitot tube, Prandtl tube, current meters etc.); flow measurement (orifices, nozzles,
mouth pieces, orifice meter, nozzle meter, venturimeter, weirs and notches).

**UNIT 4**:

Laminar Flow: Introduction to laminar flow, Reynolds experiment & Reynolds number, relation
between shear & pressure gradient, laminar flow through circular pipes, laminar flow between
parallel plates, laminar flow through porous media, Stokes law.
