A well-insulated rigid tank contains 3kg of saturatedliquid vapour-mixture of water at 250kpa. Initially, three quartersof the mass is in the liquid phase. An electric resistance heaterplaced in the tank is turned on and kept on until all the liquid inthe tank is vaporizer. Assuming the surroundings to be 25 degreesCelsius and 100kpa
Determine:
a) The exergy destruction and
b) The second law efficiency for the process.
