THER07003 2019 Thermodynamics & Fluid Mechanics Intermediate
This module introduces the basic concepts used in Thermodynamics and Fluid Mechanics.
The thermodynamics section has been designed to provide the student with sufficient tools and knowledge to solve basic real world power and efficiency problems.
Fluid mechanics is strongly biased towards the requirements of mechanical engineering, application of the basic fluid principles and concepts introduced in year 2.
