12 - A power cycle operates between a reservoir at temperature T and a lower-temperature reservoir at 280 K. At steady state, the cycle

12 - A power cycle operates between a reservoir at temperature T and a lower-temperature reservoir at 280 K. At steady state, the cycle develops 80 kW of power while rejecting 2000 kJ/min of energy by heat transfer to the cold reservoir. Determine the minimum theoretical value for T, in K.
