Essay

A geothermal electrical generating station has an actual efficiency of one- third of the ideal Carnot efficiency. For a cold reservoir temperature of $70 ^ { \circ } \mathrm { C }$ , calculate and plot the efficiency of the station as a function of the geothermal fluid temperature from $100 ^ { \circ } \mathrm { C }$ to $300 ^ { \circ } \mathrm { C }$ . If a minimum efficiency of $5 \%$ is necessary to make the utilization of the resource economical, what minimum geothermal fluid temperature is needed?
