Question: steam flows steadily through an adiabatic turbine the inlet conditions...

Question details


Steam flows steadily through an adiabatic turbine. The inlet conditions of the steam are 4 MPa, 500 °C, and 80 m/s, and the exit conditians are 30 kPa, 92 percent quality, and 50 m/s. The mass flow rate of the steam is 12 kg/s. Determine (a) the change in kinetic energy, (b) the power output, and (c) the turbine inlet area. Answers: (a) -1.95 kJ/kg, (b) 12.1 MW, (c) 0.0130 m2 Pi = 4 MPa T 500°C V1-80 m/s Steam m-12 kgls out P2 30 kPa 120.92 V2 50 m/s FIGURE P5-43
