Work at a rate of 25 kW is done by a paddle wheel on a slurry contained within a closed, rigid tank. Heat transfer from the tank occurs at a temperature of 250°C to the surroundings that, away from the immediate vicinity of the tank, are at 27°C. Determine the rate of entropy production, in kW/K, (a) for the tank and its contents as the system, and (b) for an enlarged system including the tank and enough of the nearby surroundings for the heat transfer to occur at 27°C. Assume steady state operation in both cases.
