Some issues involved in the "Water Battery" problem


   1. How much power does a typical room in the College of Science need?




   2. How many rooms are there in the College of Science?




   3. How many hours a day are the rooms used?



   4. What is the total energy used by the College of Science in one day?



       -------------------------------------------------------

   5. How high is the roof of the College of Science above the ground?

   

   6. How much energy would 1 kg of water gain as it fell to the ground?


   
   7. How many kg of water must fall to the ground each day to power
      the College of Science?



   8. How large is the area of the rooftop of the College of Science?



   9. How many kg must sit on each square meter of rooftop?



  10. How deep would a pool on top of the College of Science have to be?
