## CSM1257 - Thermodynamics and Fluid Mechanics (2012)

MODULE TITLE CREDIT VALUE Thermodynamics and Fluid Mechanics 15 CSM1257 Dr Justin Hinshelwood (Coordinator)
DURATION: TERM 1 2 3
DURATION: WEEKS 9
 Number of Students Taking Module (anticipated) 75
DESCRIPTION - summary of the module content

This module is aimed at first year students studying engineering related subjects. The two subjects are taught separately within the module as they are two distinctly different subjects. In terms of fluid mechanics, the course covers the basics of stationary and moving fluids, and covers the three main relationships of continuity, energy (Bernoullis) and momentum. In terms of Thermodynamics the course outlines the first two laws and how they relate to open and closed systems.

AIMS - intentions of the module

To provide an understanding of the basic principals of both engineering thermodynamics and fluid mechanics, and to outline their application in mining and minerals engineering.

INTENDED LEARNING OUTCOMES (ILOs) (see assessment section below for how ILOs will be assessed)

Module Specific Skills and Knowledge:

1. An understanding of the basic principles of engineering thermodynamics and fluid mechanics

2. An ability to apply the above principles in order to perform calculations and solve problems relating to theory

3. An ability to apply theory of fluids and thermodynamics to specific examples, using hand calculations and engineering software (MathCAD)

Discipline Specific Skills and Knowledge:

4. An ability in the mathematical analysis of engineering problems

5. Engineering problem solving skills using mathematical software.

Personal and Key Transferable/ Employment Skills and  Knowledge:

6. Their understanding of how to apply fundamental principles to practical applications. Using software packages to analyse problems and present reports.
