Consider a Carnot heat-engine cycle executed in a steady-flow system using steam as the working fluid. The cycle has a thermal efficiency of 34.5 percent, and steam changes from saturated liquid to saturated vapor at 275°C during the heat addition process. If the mass flow rate of the steam is 3 kg/s, determine the net power output of this engine, in kW. The enthalpy of vaporization hfg of water at 275°C is 1574.5 kJ/kg. Use data from the tables.

If the temperature goes on increasing with respect to the length (i.e temperature gradient)then it is called positive heat transfer. If the temperature gradient decreases then it is called negative heat transfer.
