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 (do not enter a percent )

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
