The aim of this module is to prepare learners for a career in a range of manufacturing /mechanical industries. This module develops on a wide range of thermal and fluidic principles which can be used in the analysis of process systems that are at the heart of a diverse range of traditional and developing industries. Project work is used to highlight the importance of ethical issues in the role of a process engineer in a manufacturing environment.

The material will be presented to the learners in the form of:
- Lectures where the learner is introduced to the topic or has their knowledge expanded. Notes provided in advance of the lectures so that students can prepare for class. This then allows for enhanced learning facilitation during lecture time where the focus is on analysis, evaluation and higher order activity.
- Tutorials where the learner applies their reading and observations to discussing solutions to problems collectively
- Laboratory based learning where the student undertakes problem solving exercises, discussion, demonstration and report writing.
- Project Clinics where the students meet with the lecturer for brief directed discussions on project development and progression.
