Question: Steam enters a two-stage adiabatic turbine at 8 MPa and 550C. It expands in the first stage to a pressure of 2 MPa. Then steam

Steam enters a two-stage adiabatic turbine at 8 MPa and 550°C. It expands in the first stage to a pressure of 2 MPa. Then steam is reheated at constant pressure to 550°C before it is expanded in a second stage to a pressure of 200 kPa. The power output of the turbine is 80 MW. Assuming an isentropic efficiency of 84 percent for each stage of the turbine, determine the required mass flow rate of steam. Also, show the process on a T-s diagram with respect to saturation lines.
