The schematic of a single-flash geothermal power plant with state numbers is given in Figure below. A geothermal resource exists as saturated liquid at 230 °C. The geothermal liquid is withdrawn from the production well at a rate of 230 kg/s and flashed to a pressure of 500 kPa by an essentially isenthalpic flashing process, where the resulting vapor is separated from the liquid in a separator and directed to the turbine. The steam leaves the turbine at 10 kPa with a moisture content of 10 percent and enters the condenser, where it is condensed and routed to an injection well along with the liquid coming off the separator. Determine the power output of the turbine?

Question
The schematic of a single-flash geothermal power plant with
state numbers is given in Figure below. A geothermal resource
exists as saturated liquid at 230 °C. The geothermal liquid is
withdrawn from the production well at a rate of 230 kg/s and
flashed to a pressure of 500 kPa by an essentially isenthalpic
flashing process, where the resulting vapor is separated from
the liquid in a separator and directed to the turbine. The
steam leaves the turbine at 10 kPa with a moisture content of
10 percent and enters the condenser, where it is condensed
and routed to an injection well along with the liquid coming
off the separator. Determine the power output of the turbine?
