Thermodynamics 1. Saturated liquid H20 at 16 MPa is fed into the boiler of a variant of a Carnot cycle (but simplified Rankin cycle) where the working fluid is not an ideal gas. Saturated H20 vapor is fed into the turbine of the same turbine. The condenser of this turbine is operated at 8 kPa. The mass flowrate of the H20 in this cycle is 7.2x103 kg/min. Draw the path of this process on T-s diagram. Estimate the thermal efficiency...

Water at 20 bar, 400°C enters a turbine operating at steady state and exits at 1.5 bar. Stray heat transfer and kinetic and potential energy effects are negligible. A hard-to-read datasheet indicates that the quality at the turbine exit is 98%. Can this quality value be correct? If no, explain. If yes, determine the power developed by the turbine, in kJ per kg of water flowing
