RATIONALE:

Mechanical engineers are expected to have the knowledge and the understanding of the basic principles and concepts of fluid mechanics both static and dynamic. This is to enable them to analyse and design systems in which fluid is the working medium.

SYNOPSIS:

This unit presents the fundamental concepts of fluid behaviour both under static
and  dynamic conditions.  This unit is designed to enable the student to analyse
and  design  fluid  systems.   The contents of this unit  includes  statics  and
dynamics  of fluid flow, potential flow, dimensional analysis, internal  viscous
flow,  eg  laminar and turbulent flows in pipes and ducts.  Also,  viscous  flow
around bodies, boundary layer and compressible flow.

OBJECTIVES:

On completion of this unit, the student should be able to: Analyse and design some of the real life flow type problems. And be able to choose a suitable simple model for the analysis to make the solution possible with the tools they have learned. Some examples of these problems are:

1. Estimation of forces on submerged bodies in static fluid situation and their stability.
2. Transporting different types of fluids in different types of applications and avoiding unwanted phenomena such as cavitation and water hammer.
3. Estimate of forces on moving, or stationary bodies caused by flowing fluids, such as drag forces on chimneys, high rise buildings, different types of constructions, aircraft's and ships.
4. Behaviour of high speed flows ie compressible flow in ducts, nozzles and diffusers.
