After completing the reading, exercises, and the associated homework you should be able to:
Find an expression for Qdot for 1-D, steady-state conduction in rectangular coordinates
Using the electrical/resistance analogy, state what's analogous to V? I? R?
Express the generic convection relation using an electrical analogy
Draw thermal "circuits" for 1-D, steady-state conduction problems and use them to find unknown temperatures, heat transfer rates, etc.
Find an expression for Qdot for 1-D, steady-state conduction in cylindrical and spherical coordinates
Explain why the rectangular coordinate expression for Rth does not work in cylindrical and spherical coordinates
Explain what a fin is, what it does and how
Explain why the conduction equation and the resistance analogy cannot be used to find the temperature distribution in, or heat transfer of, a fin
State how to use the insulated-tip BC for a fin to approximate a convective tip
Define fin efficiency mathematically
Find the temperature distribution for extended surfaces (fins)
Find the rate of heat transfer from extended surfaces (fins)
Explain what a fin effectiveness is and how it is different from fin efficiency
Use the idea of fin effectiveness to determine when it is a good idea to use a fin or not
Use fin effectiveness in calculations to determine the rate of heat transfer from individual fins and also from fin arrays
Note: Any term in bold is a key vocabulary term that you should be able to define, regardless of whether or not that is the specific learning objective.
