This unit builds on NEF1202 - ENGINEERING PHYSICS 2, as the first Thermodynamics subject for Mechanical Engineering students. It will lead to a thorough understanding of and the fluent skills of applying the Fist Law of Thermodynamics. Students will apply the First Law of Thermodynamics to various simplified engineering problems. The subject then introduces the Second Law of Thermodynamics and its relevance in setting the directions of the engineering processes. The unit elaborates on the upper limits and for some ideal processes. It then quantifies the Second Law of Thermodynamics using entropy, introduce the entropy increase principles and calculate the irreversibility changes during various engineering processes. The applications of these laws of Thermodynamics to determine the properties of the mixture of ideal gases.

Learning Outcomes

On successful completion of this unit, students will be able to:
  1. Analyse the thermodynamics properties of pure substance and apply the ideal gas law to a range of engineering situations;  
  2. Apply systematic engineering synthesis with initiative and judgement to distinguish the various closed and open systems from engineering applications;  
  3. Analyse simple engineering systems involving energy balance by applying the First Law of Thermodynamics;  
  4. Appraise the various thermodynamical systems so that these systems perform within the limits set by the Second Law of Thermodynamics;
