Consider a single flash geothermal power plant where the returning fluid is used as a heat source for an organic Rankine cycle that uses R600a as a working fluid. The well has pure saturated liquid water at 250\ deg C at a rate of 100 kg/s and the flashing ratio is 4. Remaining unknown input data should be reasonably assumed by the your. Based on the given information: Determine system energy efficiency with and without reinjection.
