A steady-flow Carnot cycle uses water as the working fluid. Water changes from saturated liquid to saturated vapor as heat is transferred to it from a source at 245°C. Heat rejection takes place at a pressure of 10 kPa. Determine the amount of heat rejected. Use steam tables. The amount of heat rejected is 2404 kJ/kg.
Carnot cycle: The Carnot cycle is an ideal thermodynamic cycle proposed by French scientist Nicolas Léonard Sadi Carnot in 1824 and further developed by others during the following decades. It establishes an upper limit on the efficiency of any classical thermodynamic engine in converting heat into work, or, conversely, the efficiency of a refrigeration system in producing a temperature difference by applying work to the system.
The working substance goes through four sequential operations. They are isothermal expansion to a desired point, adiabatic expansion to a desired point, isothermal compression, and adiabatic compression back to its initial condition in the Carnot cycle, which is an ideal reversible closed thermodynamic cycle.
