Ageothermal plant uses geothermal water (yes a liquid) extracted from beneath the earth using drilling apparatus. the geothermal water (a condensed liquid) comes up at a temperature of 200 c at a rate of 200 kg/s. it is used to drive a turbine that extracts 6000 kw of power. the water leaves the turbine at 80 c and enters a lake at 25 c. what is the actual thermal efficiency of the turbine in percent to three significant digits
Answers: 2
or 146510kW
