Task 5 from a to c

Task 5 Steam flows steadily through an adiabatic turbine. The inlet conditions of steam are 4 MPa, 500°C, and 80 m/s, and the exit conditions are 30 kPa, 92 percent quality, and 50 m/s. The mass flow rate of the steam is 12 kg/s. Steam table is available. P,= 4 MPa T= 500°C V = 80 m/s Determine: (a) the change in kinetic energy per unit mass A ke (kJ/kg) Steam (b) the change in enthalpy per unit mass A h (kJ/kg) i = 12 kg/s oul (c) the work done per unit mass (kJ/kg) (d) the power output (MW) P:= 30 kPa X= 0.92 V= 50 m/s (e) the turbine inlet area (m²)
