A turbine is supplied with steam at 40 bar, 400 °C, which expands through the turbine in steady flow to an exit pressure of 0.2 bar, and a dryness fraction of 0.93. the inlet velocity is negligible, but the steam leaves at high velocity through a duct of 0.14 m2 cross sectional area. If the mass flow is 3 kg/s, and the mechanical efficiency is 90%, calculate the power output of the turbine. Show that the process is irreversible and calculate the change of specific entropy. Heat losses from the turbine are negligible. Analyze the process using T-s diagram.

im confused, the are witch the pressure is effecting is the are that the beam is in contact with the wall, that mean that the the force is = Q=P1/A, the the A would be 300m2/100m= L3 lets call it, and then L3 x Z, Z being the thickness of the beam in the Z direction, the same applies to P2, i think there is something missing in these solutions
