A steam turbine operates with P1 = 5 MPa and T1 = 600 °C at the
inlet, an exit pressure of P2 = 100 kPa, a mass flow rate of ?̇ =
100 kg/s, and an isentropic efficiency of η = 85%. Complete a
thermodynamic analysis of the turbine, using the appropriate data
for water, by finding: (A) The temperature at the exit, T2, (B) the
work produced by the turbine, ?̇ ?, and (C) the rate of entropy

A compressor is takes in air at an inlet pressure of P1 = 80 kPa and an inlet temperature of T1 = 20oC and exhausts it at an outlet pressure of P2 =800 kPa and an outlet temperature of T1 = 200oC. Air flows through the compressor at a mass flow rate of m = 1 kg/s. Assume that the compressor is adiabatic. Find the power required to run the compressor. (Your answer will be in kW.)

A steam turbine, as shown in Figure Q3, operates at steady state with inlet conditions of Pi= 2 MPa, T1 = 480°C and producing 4000 kW. Saturated steam leaves the turbine at a pressure of 0.1 bar where it is condensed at 45.81 °C in the condenser. There is no significant heat transfer between the turbine and the condenser and their surroundings, and kinetic and potential energy changes between inlet and exit are negligible.
