Part 1 of this module is designed to develop and reinforce an understanding of thermodynamic principles and how they are applied to analyse practical problems in thermal physics.
Part 2 of the module introduces concepts relating to Medical Device development and manufacture, as well as topics such as posturography, gait, and speech analysis and rehabilitation including current state of the art technology.
Part 1 - Applied Heat
Thermodynamics laws as laws of nature independent of the structure of matter,
Derivation of expression of work done in an isothermal change of volume of an ideal gas,
Work done depends on path of change,
Concept of function of state – work and heat added not functions of state,
Change in internal energy independent of path,
Internal energy as a function of state,
The first law of thermodynamics,
