Course Aim: To introduce the fundamentals of the behaviour and analysis of the motion of fluids, and selected applications.

Intended Learning Outcomes:

On successful completion of the course, the students should be able to;

➢    solve complex fluid flow problems through the application of conservation laws of mass, momentum and energy.

➢    describe laminar and turbulent pipe flows, determine energy losses in pipelines and compute

flow and pressure in pipe systems and pipe networks.

➢    compute transient pressure fluctuations in pipelines, mass oscillations in surge tanks caused by sudden changes of discharges and introduce appropriate surge control devices

➢    apply dimensional analysis of problems and physical model testing in fluid mechanics.

➢    develop performance characteristics of positive displacement and rotodynamic machines and

select them for a specific application.

Course Content:

➢    Dynamics of fluid flow:    Design applications of force-momentum equation, torque-angular momentum, energy equation, flow measurements, frictionless flow in pipes, cavitation

➢    Laminar flow and turbulent flow in pipes: Flow classification, laminar and turbulent flow velocity profiles, friction losses, Moody diagram, local losses, pipe flow computations, pipe systems; Pipe networks, Pipe network modelling using computer software

➢    Hydraulic transients in pipes: Governing equations of unsteady flow, rigid column theory, mass oscillation in surge tanks, elastic theory, water hammer, Surge control

➢    Dimensional methods: Dimensional analysis, Pi Theorem Similitude, Dynamic similarity, Physical model studies
