Transfer Processes I

At the end of the course, students should be able to: 1. derive the heat diffusion equation and use it to predict temperature profiles across solid bodies transferring heat by conduction; 2. derive equations of heat transfer by convection and use them to predict the rate of heat loss under steady state natural and forced convection; 3. derive the equations of heat loss by radiation, and use them to predict the rate of heat loss under steady state conditions; 4. perform a procedural design of a heat exchanger for defined process requirements; 5. derive equations of mass transfer by molecular diffusion and use these to predict the flow rates and composition of output streams from a mass transfer operation under steady state conditions; 6. determine the performance and size of a given heat exchanger using different methods; and 7. perform pressure drop calculations and procedural design of different heat exchangers according to defined process requirements.
