Question:

The schematic of a single-flash geothermal power plant with state numbers is given in Fig. P10€“26, geothermal resource exists as saturated liquid at 230°C. The geothermal liquid is withdrawn from the production well at a rate of 230 kg/s, and is flashed to a pressure of 500 kPa by an essentially isenthalpic flashing process where the resulting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 a reinjection well along with the liquid coming off the separator. Determine
(a) The mass flow rate of steam through the turbine,
(b) The isentropic efficiency of the turbine,
(c) The power output of the turbine, and
(d) The thermal efficiency of the plant (the ratio of the turbine work output to the energy of the geothermal fluid relative to standard ambient conditions).
