STAFFING:

PRE-REQUISITE(S)

64613 or 75613+70341

RATIONALE:

Mechanical  engineers  are  expected to have  the  knowledge  and  the
understanding of the basic principles and concepts of fluid  mechanics
both  in  static  and dynamic conditions. 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 any practical problem in which fluid
is  the working medium. The contents of this unit includes statics and
dynamics  of fluid 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. The  theoretical
knowledge is reinforced by practical work, videos and a project.

OBJECTIVES:

On completion of this unit, the student should be able to:
Analyse and design may 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. Estimation 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.
