A 0.3-m3 rigid tank initially contains nothing, is connected by a valve to a steam line at 0.8 MPa and 300°C. The valve is now opened, and the steam is allowed to enter the tank. The valve is closed when the tank reaches 0.6 MPa and 200°C. The tank exchanges heat during this process with the surroundings at 25°C, 100 kPa. Determine (a) the amount and direction of heat transfer between the tank and the surroundings, (b) entropy generation during the process, (c) exergy destroyed, (d) exergy at the final state, (e) exergy input due to mass input during the process, (f) the work potential of the tank at the final state of the process, and (g) the irreversibility of the process
