Question:

Steam enters the adiabatic turbine of Fig. 4.50 at 10 MPa and 600°C. If the mass flow rate of the steam is 2 kg/s, determine the power output of the turbine if the steam leaves at
a) 20 kPa with x = 0.9,
b) 10 kPa with x = 1,
c) AT 20 kPa with s2 = s1 (use s, which is entropy, as given in the tables).
