- Compare and contrast parallel, cross, and countercurrent flow in heat exchangers.
- Determine the needed surface areas and/or fluid flow rates for heat exchangers given unit operation or process energy needs.
- Calculate and explain heat exchanger efficiency.
- Predict likelihood and account for consequences of fouling.
- Define radiation terminology such as blackbody, grey surface, emissivity, etc.
- Relate surface temperature to radiation wavelength and energy.
