Consider a heat transfer process of the steady form that occurs along a plain wall. While the inner room temperature was kept at 25 °C, the outdoor environment temperature was measured to be 2 °C. If the heat transfer at this plain wall in an hour is 3,528 kJ, determine the .total exergy destruction per unit time (the rate), which occurs during this heat transfer process, a) use the total entropy generation to find the rate of the total exergy destruction in the room (i.e., use the entropy balance), b) use the exergy balance to find the rate of the total exergy destruction in the room

A fluid at 0.7 bar occupying 0.06 m is compressed reversibly to a pressure of 95 bar and specific volume of 0.7 mkg according to the law pv" =c The fluid then expands reversibly according to the law p=c to 3 bar. A reversible cooling at constant volume then restores the fluid back to initial state Calculate the work for the compression in the process.

78 kg of water vapor is found as saturated vapor at 650 kPa pressure in a cube-shaped container with a fixed volume. The cube lost heat and its pressure dropped to 325 kPa. Since the environmental conditions are 100 kPa 25 ºC, find the exergy change of the steam in the first and the last state, the exergy change in the steam, the exergy destruction and the second-law efficiency for this process change.
