Steam flows steadily through an adiabatic turbine. The inlet conditions of the steam are 4 MPa, 500C, and 80 m/sand the exit conditions are 30 kPa, 92 percent quality, and 50 m/s. The mass flow rate of the steam is 12.4 kg/s. The properties of the steam arev₁= 0.086442 m³/kg,h₁= 3446 kJ/kg, andh₂= 2437.7 kJ/kg.

Determine the turbine inlet area.

The turbine inlet area is m².
