    A power plant taps steam superheated by geothermal energy to 421 K (the temperature of the hot reservoir) and uses the steam to do work in turning the turbine of an electric generator. The steam is then converted back into water in a condenser at 321 K (the temperature of the cold reservoir), after which the water is pumped back down into the earth where it is heated again. The output power (work per unit time) of the plant is...

    In Geothermal-steam power cycle, the source of heat is the hot water from well. The heat exchanger receive hot water at Tg1= 105 oC and the water leaves at 40 oC as shown in Figure 3. Steam exits the boiler at 40 bar, 300 oC, and it exits the turbine at 1 bar. Saturated liquid water exits the condenser at 1 bar. The plant operate to generate 20 MW electric power with generator efficiency of 0.95. The isentropic efficiency of...

    A geothermal source provides water at 400°F, 140 psia to a heat exchanger that boils an organic liquid. Condenser cooling water is available at 70°F and there is a 10°F ∆T across the condenser (which is a second counterflow heat exchanger) at the cooling water inlet. (a) If the minimum allowable ∆T across the geothermal water heat exchanger is 15°F, what is the maximum theoretical thermodynamic efficiency that could be expected of such a cycle? (b) How many cubic feet...

    CHAPTER 10 10-136 A 10-MW geothermal power plant is being consid- ered at a site where geothermal water at 230°C is available. Geothermal water is to be flashed into a chamber to a lower pressure where part of the water evaporates. The liquid is returned to the ground while the vapor is used to drive the steam turbine. The pressures at the turbine inlet and the tur- bine exit are to remain above 200 kPa and 8 kPa, respec- tively....

    (30 points) We are designing a geothermal flash steam power plant that pumps water from underground geothermal reservoirs at 180 °C at 5 MPa to a tank at 150 °C. Some of the water flashes to produce saturated steam that is sent to a turbine and a water stream that is returned to the well. The output of the turbine is at 0.1 MPA. Assume that the system is well insulated. Determine: a. The flowrate of steam leaving the flash...

    Consider geothermal hot water at P1 and T1; it is throttled to P2 in a unit called a flasher and satu rated vapor is used to drive a turbine which exhausts a wet mixture at P3. The saturated liquid is returned back to the ground. As flash pressure P2 is decreased, more vapor is produced and hence, more mass of vapor is sent to turbine. However, expansion ratio in turbine is reduced with reduced work output per unit mass of...

    Pleases help me thanks. 5 kg of liquid water at 100°C was converted to steam at 100°C by boiling at standard atmospheric pressure, in the arrangement of the figure below. The volume of the water changed from an initial value of 0.005 mº as a liquid to 8.355 mº as steam. Latent heat of vaporization for water Lv = 2256 kJ/kg. Standard atmospheric pressure is 1 atm or 1.01 x 109 Pa. Loaded Piston Steam Insulation Insulation Liquid water Thermal...
