A tank of volume 1 m3 initially contains steam at 60 bar, 3208C. Steam is withdrawn slowly from the tank until the pressure drops to 15 bar. An electric resistor in the tank transfers energy to the steam maintaining the temperature constant at 3208C during the process. Neglecting kinetic and potential energy effects, determine the amount of entropy produced, in kJ/K.
