Conservation of energy In 1845 James Prescott Joule suggested that the water at the bottom

 

4. Conservation of energy In 1845 James Prescott Joule suggested that the water at the bottom of a waterfall should be warmer than at the top. In particular, for Niagara Falls (a height of about 50 m) the temperature difference would be approximately 0.12 ?C. How would you go about calculating this number? Unlike in 1845 most of the water nowadays is diverted through hydroelectric power schemes. How does this affect Joule’s prediction? Comment: How do you know (assuming Niagara behaves as any other waterfall!) this must be an overestimate?
