Synopsis

This unit develops the students' physical understanding of the bases of fluid flow and translates that into the ability to formulate and solve problems. It covers the topics of basic concepts and fluid properties, hydrostatics, control volume analysis, the Bernoulli equation, pipe flow and pumps, non-Newtonian flow, dimensional analysis, boundary layers, fluid forces in flow - lift and drag and 2-phase flow.

Outcomes

To be able to formulate and analyse hydraulics problems in fluids and to be able to calculate the forces on bodies in a quiescent fluid, including the effects of buoyancy.
To be able to calculate forces on bodies in fluids undergoing rigid body motion.Use control volumes to predict fluid behaviour with particular regard to the principles of continuity, momentum and energy, and the Bernoulli equation.
Use dimensional analysis and modelling to plan experiments, to present results meaningfully and to predict prototype performance.
Calculate lift and drag forces for bodies subjected to fluid motion.
Compute flow rates and pressure drops in pipe networks under steady state conditions.
Understand the typical operation and applications of Pumps, Fans, Compressors and Turbines, their capabilities and limitations, and operating parameters that significantly affect performance.
To be able to select the appropriate pump or fan for a particular pipe network and flow.
To classify non-Newtonian Fluids, use constitutive equations for these fluids to predict pressure drops in different flows
Calculate the lift and drag on vehicles of different geometries travelling at a variety of speeds and to determine the consequent effect on fuel consumption.
Carry out simple experiments relating to fluid properties and flow behaviour.
To be able to solve problems by defining the problem using the discipline theory taught and applying mathematical and other methods taught throughout the curriculum.

Assessment

Tests, tutorials and laboratory assignments: 30%
Examination (3 hours): 70%
Students are required to achieve at least 45% in the total continuous assessment component (assignments, tests, mid-semester exams, laboratory reports) and at least 45% in the final examination component and an overall mark of 50% to achieve a pass grade in the unit. Students failing to achieve this requirement will be given a maximum of 45% in the unit.
