Find the heat transfer out of the extra work

Reference no: EM131233508

A 1-kg rigid steel tank contains 1.2 kg of R-134a at 20?C, 500 kPa. Now the setup is placed in a freezer that brings it to -20?C. The freezer operates in a 20?C kitchen and has a COP that is half that of a Carnot refrigerator. Find the heat transfer out of the R-134a, the extra work input to the refrigerator due to this process, and the total irreversibility including that of the refrigerator.
