1 gal. = 8 Lbs. = 3.63 kg.
M = 10,000gal * 3.63kg/gal. = 36,320 kg.
PE = M*g*h = 36,320*9.8*61.5 Joules.
What is the total amount of potential energy that can be stored in a 10,000 gallon water tower built with the water tank 61.50 m above ground level?
<hint: You will need to look up the mass of a gallon of water in Kilograms>
