You want to designa geothermal power plant.

1.Look up the temperatures Tc of a typicalwinter day and Th of the hot reservoir, located kilometers underground. What is the maximum possible efficiency attainable by this plant?

2.Which geothermal power plant in Icelandproduces the most electrical power? What is its capacity (in watts)? How many homes, on average, can this plant power?

3.What is the rate of heat Qc that this plant expels to the environment? You may assume the same efficiency calculated in part 1.

4.In order to sustain this heat output, what is the mass flow rate m of steam needed to cycle through the wells? Assume that the steam does not condense. The specific heat capacity of steam isc = 1865 J*kg^1*K^1
