Steam enters an adiabatic turbine at 6 MPa, 600°C, and 80 m/s, and leaves at 50 kPa, 100°C, and 140 m/s (T0 = 25°C, P0 = 100 kPa). If the power output of the turbine is 5 MW, determine:
a) The mass flow rate of the steam flowing through the turbine,
b) The isentropic efficiency of the turbine,
c) The change in total exergy between the inlet and the outlet of the turbine, and
d) The exergetic efficiency of the turbine.
