Repeat Prob. 7120 for a turbine efficiency of 85 percent. Data From Q#120: Steam at 3 MPa

Question:

Repeat Prob. 7–120 for a turbine efficiency of 85 percent.

Data From Q#120:

Steam at 3 MPa and 400°C is expanded to 30 kPa in an adiabatic turbine with an isentropic efficiency of 92 percent. Determine the power produced by this turbine, in kW, when the mass flow rate is 2 kg/s.
