A mass flow of 10kgs of water vapor at 30bar and 5000c, Ask an Expert

Academics

A mass flow of 10kg/s of water vapor at 30bar and 500⁰C flows steadily through the inlet an insulated turbine. The pressure of the water is reduced to 1bar at the turbine outlet. Neglecting kinetic and potential energy effects, determine:

a) The maximum power output in kW generated by the turbine and its corresponding outlet temperature.

b) The actual power output in kW generated by the turbine and its corresponding outlet temperature if its adiabatic efficiency is 90%.

c) Sketch the reversible and irreversible processes in a T-s diagram.
