AIM/PURPOSE

To develop a sound understanding in the theory and application of thermodynamics, especially as related to heat engines, process and environment heating/cooling.

LEARNING OUTCOMES

On successful completion of this course, the student should be able to:

1.            Demonstrate an understanding of the laws of thermodynamics.

2.            Analyse common IC engine cycles and explain their operation and their effects on the environment.

3.            Demonstrate an understanding of process heating/cooling systems.

4.            Explain nozzle terminology and calculate velocities and pressures.

5.            Outline HVAC system operation and equipment and determine heating, cooling and hehumifing loads.

6.            Determine air/fuel ratios and exhaust analysis for common fuels and describe their handling requirements.
