The thermal efficiency of a heat engine operating according to the Carnot cycle is 28% and water vapor is used as the working fluid. The heat transfer to the working fluid is at a temperature of 350 ° C, and at this time, the fluid transforms from a saturated liquid to a saturated vapor. a) Calculate the degrees of dryness when the release of heat from the working fluid to the cold heat source begins and ends. b) Since 5 kg of fluid is circulating in the cycle per hour, find the power of this heat engine by using the evaporation entropy.
