Question

Repeat Problem 3, but this time, treat the steam as an ideal gas with cp = 2.083 kJ/kg-K, which is its value at about 700 K. (You will need to determine Rg = Ru/MWwater, with MWwater = 18.0 kJ/kg-K, as well as k = cp/cv). You’ll find that the ideal gas model is not too bad for water vapor under these conditions.

Steam enters an adiabatic turbine at 8 MPa and 700 C with a mass flow rate of 3 kg/s and leaves at 1 MPa. The isentropic efficiency of the turbine is 0.90. Neglecting the kinetic energy change of the |steam, determine (a) the temperature at the turbine exit and (b) the power output of the turbine (Use the Steam Tables to determine properties of the H20) Repeat Problem 3, but this time, treat the steam as an ideal gas with cp = 2.083 kJ/kg-K, which is its value at about 700 K.
