During steady-state operation, a gearbox receives 60 kW through the input shaft and delivers 58.8 kW of power through the output shaft. For the gearbox as the system, the rate of energy transfer by convection is 1.2 kW and T= 20C is the temperature of the immediate surrounding air. Evaluate the rate of entropy production for (a) the gearbox as the system and (b) an enlarged system consisting of the gearbox and the immediate surroundings. 60 KW System- boundary S T-300 K- 1.2kW 58.8 kW Gearbox Moran, J.
