The energy equation contains work and heat terms. address the following questions. a. in terms of energy analysis, describe the "real life" work components (i. e. types of work) that we might have to account for in this course when using the energy equation. also, list mathematical equations for each type of when you can. b. the energy equation has the "unsteady term" (just to the left of the equal sign). describe two situations in an energy analysis when you might have to perform an unsteady energy analysis (versus steady flow).
