Steam enters a turbine operating at steady state at 2 MPa, 390 C with a velocity of 82 m/s. Saturated vapor exits at 0.1 MPa and a velocity of 43 m/s. The elevation of the inlet is 2 m higher than at the exit. The mass flow rate of the steam is 19 kg/s, and the power developed is 5 MW. Let g = 9.81 m/s. Determine the area at the inlet, in cm.
