Skills outcomes
Students should gain a sound knowledge of the terminologies used, of the fundamental laws of engineering science and be able to perform basic level calculations in the key subject areas of mass balance, energy balance, engineering thermodynamics, fluid mechanics, heat transfer, chemical thermodynamics and reaction kinetics.
Students will apply theoretical concepts, e.g. heat transfer to computer based solutions (design).
