Objectives

Applications of the three fundamental equations in Fluid Mechanics i.e. continuity, energy and momentum equations together with a study of turbulent flow in pipes.

Syllabus

Fluid Dynamics: The continuity equation.  Bernouilli’s equation. The kinetic energy correction factor.  Application of the energy equation.  Nozzles and diffusers.  Flow meters, the Venturi and Orifice Plate meters.  Flow over notches and weirs.  Flow through orifices.  Time to empty tanks.  The pitot-static tube.  Impact of jets.  Flow Meters: The rotameter, the turbine flow meter, the bend (elbow) flor meter, Venturi and orifice plate meters.

Turbulent Flow in Pipes:  The frictional head loss and pressure loss equation.  Reynolds number.  The friction factor.  Use of formulae and Moody chart for its determination.  Power required to overcome friction.  Secondary losses.  Losses in sudden and gradual expansions and contractions.  Pipes in series and in parallel.  Pipe flow examples.

The Momentum Equation:  The impact of fluid jets on fixed vanes.
