Solve the following problem using EES. Steam flows steadily through an adiabatic turbine. The inlet conditions of the steam are 4 MPa, 500\deg C and 80 m/s, and the exit conditions are 30 kPa, 92% quality and 50 m/s. The mass flowrate of the steam is 12 kg/s. Investigate the effect of the turbine exit pressure on the power output of the turbine. Let the exit pressure vary from 10 to 200 kPa. Plot (1) T2 vs P2 and 2) Plot the power output (W_dot_T in MW) against the exit pressure (P2 in kPa) and discuss the results.
