Fluid Mechanics


The aim of this module is to provide the learner with a fundamental comprehension of fluid mechanics, the branch of mechanics associated with the static and dynamics of fluid flow.  Fluid mechanics is fundamental to many industrial processes and device design.  Starting from the definition of a fluid, learners build up their knowledge to describe, characterise and analyse the behaviour of steady fluids flows.  Learners are introduced to the theoretical formulation of concepts of mass, momentum and energy conservation, as well as the application of such.  The course is designed such that learners emerge with the tools and knowledge to solve real life problems relating to fluid flow.      

Learning Outcomes

  1. Define, derive and manipulate the concepts of pressure, hydrostatic pressure and buoyancy.  Apply principles to problem-solving involving same.

  2. Describe the concept which underpins Reynolds Transport Theorem (Total and Convective derivative) and to be able to use both the flow continuity (i.e. law of mass conservation) and Bernoulli's equation (i.e. law of energy conservation) to calculate (pressure, velocity and height) heads in a 1D flow.

  3. Compile and report in a clear concise manner the findings of laboratory experiments concerning the operation of flow measuring devices.

  4. Describe the concept of inviscid flows and thereafter be able to use inviscid flow momentum theory to calculate forces exerted on both stationary and moving bodies by fluid flows.

  5. Demonstrate an awareness of the Reynolds number, Laminar, Turbulent Flow, Hagen-Poiseuille Flow, Coutte Flow, Friction Factors, Darcy Equation and the entry length requirements for pipeline flow

  6. Approximate pressure losses associated with friction and fittings in pipelines for both laminar and turbulent flows and be able to read Moody Diagrams to account for the relative roughness of a pipeline. Additionally the learner should be able to distinguish between minor and major losses
