1 kg of air is in a tank at a temperature of 22 °C and a pressure of 160 kPa. The rotating blade, which is rotated by an external power source in the tank, increases the temperature in the tank up to 60 °C. Since there is a heat transfer of 50 kJ from the system to the surroundings and the ambient air temperature To = 22 °C, for this process:   a) Exergy extinction   b) Calculate the reversible work.
