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).

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.
