Q2. The schematic of a single-flash geothermal power plant with state numbers is given below. Geothermal resource exists as saturated liquid at (260.5) °C. The geothermal liquid is withdrawn from the production well at a rate of 222 kg/s, and is flashed to a pressure of 550 kPa by an essentially isenthalpic flashing process where the resulting vapor is separated from the liquid in a separator and directed to the turbine which is working ideally. The steam leaves the turbine at 10 kPa with a moisture content of 13 percent and enters the condenser where it is condensed and routed to a reinjection well along with the liquid coming off the separator. Draw the T.S diagram and Determine (a) the mass flow rate of steam through the turbine,
