QI A cyclic steam power plant is to be designed for a steam temperature at turbine inlet of 360 °C and an exhaust pressure of 0.08 bar. After isentropic expansion of steam in the turbine, the moisture content at the turbine exhaust is not to exceed 15%. Determine the maximum allowable steam pressure at the turbine inlet and calculate the Rankine cycle efficiency for these steam conditions. Also estimate the mean temperature of heat addition. [Ans. 16.83 bar, 31.7%, 187.5 °C]
