In a single-flash geothermal power plant, geothermal water enters the flash chamber (a throttling valve) at 230°C as a saturated liquid at a rate of 50 kg/s. The steam resulting from the flashing process enters a turbine and leaves at 20 kPa with a moisture content of 5 percent. Determine the temperature of the steam after the flashing process and the power output from the turbine if the pressure of the steam at the exit of the flash chamber is (a) 1 MPa, (b) 500 kPa, (c) 100 kPa, (d) 50 kPa.

Question
In a single-flash geothermal power plant, geothermal
water enters the flash chamber (a throttling valve) at 230°C
as a saturated liquid at a rate of 50 kg/s. The steam resulting
from the flashing process enters a turbine and leaves at
20 kPa with a moisture content of 5 percent. Determine the
temperature of the steam after the flashing process and the
power output from the turbine if the pressure of the steam
at the exit of the flash chamber is (a) 1 MPa, (b) 500 kPa,
(c) 100 kPa, (d) 50 kPa.
