Humid air enters an adiabatic turbine at P1 = 300 kPa and T1 = 190°C with 7.5% relative humidity. The flow exits the turbine in saturated conditions at P2 = 100 kPa. If mass flow rate (of dry-air) is 2.5 kgd.a./s, determine: a. The absolute humidity at the inlet. b. The temperature T2 of the flow at the outlet. c. The power produced by the turbine in kW. d. Sketch this process on a psychometric diagram.
