Exergy Destruction during Expansion of Steam. A piston-cylinder device contains 0.05 kg of steam at 1 MPa and 300°C. Heat is added to the piston at 30kJ and 300K. Steam now expands to double its volume, doing work. Heat losses from the system to the surroundings are estimated to be 2 kJ during this process. Assuming the surroundings to be at To 25°C and Po 100 kPa, determine the exergy destroyed.
