1. An energy system can be approximated to simply show the interactions with its environment including cold air in and warm air out, heat transfer inflow and power input. a. Write a first law balance around the system and solve for the rate of work output to the system. Assume Cpair = 1.005 kJ/kg/K. b. Determine the performance coefficient of the cycle. c. Write a second law balance around the system and determine the rate of entropy production. d. Determine the exergy destruction rate, assume To = 290 K. Qdot, in = 60 kW Mdot,air = 4 kg/s, T = 293 K Tb = 273 K Mdot,air = 4 kg/s T = 313 K Wdot = ?
