1. (3 Points) Air (as an ideal gas) is compressed in an adiabatic compressor from an initial state of 100 kPa and 300K to a final state of at 200 kPa and 600K. Determine the change in specific entropy of air during this compression process. 2. (3 Points) A heat engine operates between two temperature limits of 1300 K and 400 K. It receives 1.2 MJ of heat while producing 500 kJ of useful work. Determine: a. The exergy of the heat received by the heat engine. b. The energy that is not available for work production. c. The irreversibility of the process.
