Unit Description and General Aims
The objective in presenting this unit is to provide students with detailed knowledge of the principles and practices governing the field of thermodynamics.
The subject matter covered in the unit will include thermodynamic laws and their applications; steam and gas power cycle concepts; the use of steam and Mollier charts; thermodynamic relationships; applied thermodynamic concepts in relation to internal combustion (IC) engines, steam turbines, and air compressors and refrigeration cycles.
At the conclusion of this unit, students will have been imparted with the requisite knowledge to comprehend, distinguish, and apply the principles and practices governing the field of thermodynamics in their future work.
On successful completion of this Unit, students are expected to be able to:
- Identify and apply basic thermodynamic principles and concepts.
