A Carnot heat engine with specific amount of air executes a Carnot Cycle. The engine receives heat from thermal reservoirs at 227°C and rejects the waste heat to the ambient at 37 °C. The pressures at the initial and final states of the heat addition are 2.8 MPa, and 1.4 MPa respectively. (a) Sketch the cycle on p-v coordinates and then determine: (b) the work and heat transfer for each of the four processes, in kJ/kg. (c) the pressure and volume at the beginning of the isothermal compression in kPa (d) the efficiency of the cycle th
