A close rigid tanks with a volume of 2 m3 contain hydrogen gas initially at 320 K and 180 kPa. Heat transfer from a reservoir at 500 K takes place until the gas temperature reaches 400 K.
Calculate the entropy change and entropy production for the hydrogen gas during the process, both in kJ/K, if the boundary temperature for the gas is the same as the gas temperature throughout the process and Determine the entropy production, kJ/K for an enlargers system which includes the tank and reservoir
