A geothermal resource exists as saturated liquid at 200oC. The geothermal liquid is withdrawn from a production well at a rate of 200 kg/s, and is flashed to a pressure of 500 kPa by an essentially isenthalpic flashing process, where the resulting vapor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 is directed to the turbine. Steam leaves the turbine at 12 kPa with a moisture content of 14% and enters the condenser, where it is condensed and routed to a reinjection well, along with the liquid coming from the separator. Determine
(a) The mass flow rate of steam through the turbine and
(b) The power output of the turbine.
