A adiabatic R-134a compressor has an inlet state of 100 kPa, -10 °C and an exit state of 60 °C, 600 kPa. The dead state temperature and pressure is 22°C and 97 kPa, respectively. Find the compressor's (a) isentropic efficiency, (b) second law efficiency, (c) reversible work, (d) irreversibility, and (e) exergy destruction.
(a) Draw a schematic of the system and (b) determine if the inventor's claims are true.
No heat interactions with the environment are allowed. You do not need to describe the details of the process that produces the maximum work, but you do need to describe the final state of the blocks fully.
