Thermodynamics is concerned with heat and its relationship with energy and work, such as in engines. Fluid mechanics, meanwhile, is the study of fluids and forces on them. Aimed at students of engineering subjects, this course covers these two areas in parallel. The fluid mechanics component of the module covers the basics of stationary and moving fluids, and covers the three main relationships of continuity, energy (Bernoulli’s) and momentum.The thermodynamics component outlines the first two laws and how they relate to open and closed systems.
 

This module aims to provide you with an understanding of the fundamental principles of engineering thermodynamics and of fluid mechanics.The aims are as follows:

- appreciate the relevance of the laws of thermodynamics to your discipline;
- understand the effects of hydrostatic forces;
- appreciate the forms of energy transferred by fluid flows.
