Answer part d


Question No. 4 4. Steam enters an adiabatic turbine steadily at 7 MPa, 500°C, and 45 m/s, and leaves at 100 kPa and 75 m/s. If the power output of the turbine is 5 MW and the isentropic efficiency is 77 percent, draw the process on a T-s diagram and determine: (a) the mass flow rate of steam through the turbine (b) the temperature at the turbine exit. (c) the rate of entropy generation during this process (d) the second law efficiency of the steam turbine. Note: Let To-25°C, and Po is 100 kPa.
