Aims

To provide students with an engineering foundation in the principles of engineering analysis and design. It covers concepts key to the understanding of the performance of processes for the manufacture of biologically-based products and for the specification and design of overall process sequences. The course is a pre-requisite for 2nd year and 3rd year modules.
