If high temperature energy is available at 1100°F to a steam power plantand if the temperature of a river nearby is 60°F, what is the maximumpossible efficiency of this heat engine? An inventor claims absorbing heat at 300°C and rejecting heat to the surroundings at 15°C with n = 60%. Is this engine possible? How does the outside air temperature affect the COP for a Carnot heat pump Assume TH = 298 K and 253K
