g An energy system can be approximated to simply show the interactions with its environment including cold water in and warm water out, heat transfer inflow and power output. a. Write a first law balance around the system and solve for the rate of work output from the system. Assume CP, WATER = 4.18 kJ/kg/K. b. Determine the thermal efficiency of the cycle. c. Write a second law balance around the system and determine the rate of entropy production. You can use equation (6.13) for the entropy change in water. d. Determine the exergy destruction rate, assume T0 = 295 K.
