thermo question
2. (20 points) Steam enters a turbine operating at steady state at 2 MPa, 360°C with a velocity of 100 m/s. Saturated vapor exits at 0.1 MPa and a velocity of 50 m/s. The elevation of the inlet is 3 m higher than at the exit. The mass flow rate of the steam is 15 kg's, and the power developed is 7 MW. Let g -9.81 m/s Determine (a) the area at the inlet, in m, and (b)...

A steam turbine, as shown in Figure Q3, operates at steady state with inlet conditions of Pi= 2 MPa, T1 = 480°C and producing 4000 kW. Saturated steam leaves the turbine at a pressure of 0.1 bar where it is condensed at 45.81 °C in the condenser. There is no significant heat transfer between the turbine and the condenser and their surroundings, and kinetic and potential energy changes between inlet and exit are negligible.
