1st order modelling 11 - heat exchanger

Looks at the modelling of a heat exchanger which has liquid flowing in at one temperature, being mixed in a tank in the presence of heating and then exiting tank at same flow rate. It is shown that his model has simple first order dynamics, but is represented as having two inputs rather than one. Lectures aimed at engineering undergraduates. Presentation focuses on understanding key prinicples, processes and problem solving rather than mathematical rigour.
