This module will introduce students to the principals of fluid mechanics and will also lay the foundation for fluids mechanics. Students will apply these principles to the solution of engineering problems such as pipe sizing and the selection of system components such as valves and pumps.
Introduction to Fluid mechanics: Why we study fluid mechanics, units, dimensional formulae, pressure, state, shear stress, viscosity, compressibility.
Fluids at rest: Pressure considerations, Pascals law, pressure variation in liquids. Force considerations,- Forces on submerged surfaces , buoyancy: Archimedes principle, stability of completely submerged bodies, stability of floating bodies.
Bernoulli: Application of Bernoulli equation, steady flow energy and continuity equations, venturi meter, pitot static tube.
Instrumentation: Pressure measurement and flow measuring techniques.
Fluid Dynamics and viscosity: Definitions of viscosity, shear stress in a liquid, laminar and turbulent flows, flow characteristics, pressure drop in a pipe
Pumped systems: Pump types, pump and system characteristics, pumps in series and parallel, pump flowrate, head and power. Single line pipework systems including a pump and elevation changes. Pipe types and sizes, valves and fittings.
