DESCRIPTION - summary of the module content

This is an applied module, developing the understanding of the continuity and energy equations to solve fluid problems of relevance to both mining and renewable applications. An appreciation of energy loss in fluid flows is developed and dimensional analysis techniques are taught and applied to wide range of analytical and experimental situations.

Pre-requisites: Fluid Mechanics and Thermodynamics CSM1257, or any equivalent knowledge of a 1^st year university course on covering the basics of fluids and thermodynamics.

The module is based on typical engineering undergraduate course but the engineering skills covered are directly important for mining and renewable energy fields.

Some of the content of the module may be useful for civil engineering based discipline.

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.
