Unit Code: MCD534

Unit Name: Fluid Mechanics and Machinery

Description: Engineering Technologists are expected to have a broad knowledge of the principles of fluid mechanics and the techniques used to predict the behaviour of fluids in engineering applications. This unit will begin by looking at the forces exerted by a static fluid on immersed surfaces and the concept of the centre of pressure. It also examines a range of hydraulic devices and systems that incorporate hydraulic pressure transmission. Learners will then examine viscosity in fluids, its measurement and the characteristics of Newtonian and non-Newtonian fluids. Technologists would be able to determine the behavioural traits and parameters of static fluid systems, understand the effects of viscosity in liquids, and select the behavioural characteristics and parameters of actual fluid flow.

Learning Target Outcomes: On successful completion of this course, students should be able to: 1. Analyze the head-loss due to friction and fittings in the fluid system. Demonstrate the use of pressure and flow measurement devices such as manometric and barometric devices. 2. Demonstrate a traverse of a flow section in a round pipe using a Pitot tube, plot the velocity profile and confirm the flow rate using a venturi meter. Analyze the force exerted by a jet of liquid striking a: flat plate, curved surface, moving blade. Perform fluid experiments 3. Analyze flow in an open channel using Chezy and Manning formula and determine the Chezy coefficient. Distinguish the viscosity of different liquids using a recognized technique. 4. Analyze the experimental results with theoretical calculations of Fluid mechanics problems using Bernoulli’s Equation 5. Design and assemble a hydrostatic transmission circuit and determine the pressures and flows to ascertain the correctness of the design. Calculate the head-loss due to friction and fittings in the fluid system and compare the results with different fittings. 6. Distinguish the most efficient pump and its location in a fluid system for its purpose. Demonstrate a traverse of a flow section in a round pipe using a Pitot tube, plot the velocity profile and confirm the flow rate using a venturi meter. 7. Analyze flow in an open channel using Chezy and Manning Formula and determine the Chezy coefficient.
