Saturated vapor steam with 0.5kg/s at 200 kPa exits a turbine. The system needs a compressor to supply air at 500 kPa with a rate of 0.1 kg/s. The coupled system is shown in the following figure. Assume the system is adiabatic and reversible. The inlet properties of the air to the compressor are 100 kPa, 20°C. Determine: a) The inlet pressure of the steam to the turbine (25 points). b) The inlet temperature of the steam to the turbine (15 points). c) If the turbine isentropic efficiency is 70%, find the actual turbine power (20 points). d) What is the effect of part (c) on the properties of the exit air in detail (20 points)? and e) Sketch the T-S and P-V diagrams for both expansion and compression processes (Show all values and required labels on it) (20 points). $+$ Turbine Compressor
