DESCRIPTION - summary of the module content
AIMS - intentions of the module
The aim of this course is to (i) extend on the basic principles of the Thermodynamics and Fluid Mechanics module, particularly with respect to fluid flow, and (ii) expand on the relevance of these principles to real life situations such as flow in pipelines and the design of pump and hydraulic systems.
INTENDED LEARNING OUTCOMES (ILOs) (see assessment section below for how ILOs will be assessed)
SYLLABUS PLAN - summary of the structure and academic content of the module
Dimensions units and the concept of Dimensionless Ratios. Identifying Dimensionless ratios using Rayleigh and Buckingham p methods, Hydraulic similarity and the testing of models. Review of key principles – Continuity & Bernoulli’s equations, Dynamic & Kinematic viscosity, Reynolds Experiment – Laminar and turbulent flow regimes and Reynolds Number. Laminar flow in pipes – pressure drop during laminar flow, Poiseulles equation, development of laminar flow in pipes, relationship between average and maximum velocities Turbulent flow in horizontal pipes - friction factor and use of Moody diagram, Pressure losses in pipes due to friction, Darcy’s law in pressure and head form Frictional pressures losses during flow in non-horizontal pipes and pipes of varying diameters. Minor losses in pipes due to expansions & contractions; Flow in pipelines between reservoirs: relationship between losses and head, branching pipelines and parallel pipelines. Open Channel Flow: definition of wetted perimeter, hydraulic mean depth, hydraulic gradient, Chezy and Mannings equations for discharge, solving discharge equation for depth of flow, channel proportions for maximum discharge. Pumps and pumping: Types of rotadynamic pumps, pump efficiency, derivation of pump affinity laws, pump characteristic curves, losses in rising mains, pump performance in series and parallel.
