You are a particularly bright caveman tired of living in an unheated and unlighted cave. In front of your cave there are 2 geysers (continuously flowing fountains of hot water that you can model as an incompressible fluid with a specific heat capacity of c = 4.2 kJ/kg-K; the water does not undergo any type of phase change). Geyser A puts out mfA = 1 kg/s of water at a temperature of TA = 310 K while geyser B puts out mfB = 0.15 kg/s of water at a temperature of TB = 370 K. The ambient temperature is To = 290 K.
If you wanted to use one of the geysers to as a resource to produce electricity and light your cave then which geyser would you choose and why?
What is the maximum rate of electricity that can be produced using each of the geysers?
