Reconsider Prob. 18-121. The flow rate of geothermal water at the flash chamber inlet is 50 kg/s. The vapor resulting from the flashing process is routed to a steam turbine whose isentropic efficiency is 88 percent. The steam leaves the turbine and enters a condenser maintained at 20 kPa. Determine the power output from the turbine.
Prob. 18-121
Geothermal water enters a flash chamber at a temperature of 210oC as a saturated liquid. The pressure of water is decreased to 600 kPa at the exit of the flash chamber. Determine the temperature and the fractions of liquid and vapor phases after the flashing process.
