According to the Carnot cycle, the thermal efficiency of a working heat machine is 28%, and water vapor is used as the working fluid. Heat transfer to the working fluid occurs at 350°C, and at this time the fluid passes from a saturated liquid state to a saturated vapor state. Since 5 kg of fluid circulates per hour in the cycle, find the power of this heat machine using the entropy of evaporation.
