Problem Idea

June 18, 2010

In the WCYDWT vein, I’m wondering what the net gain in water pressure is between the force required to pump the water into a water tower and the resulting water pressure created by the tower.

I’m thinking the problem would break down to:

  • Force required to lift x gallons of water y feet
    • Work = Force x Distance
    • Force = Mass x Acceleration
    • Gravity’s got to factor in here somewhere, because obviously it takes more work to pump water vertically than horizontally.
  • Force produced by x gallons of water descending y feet
    • Interesting article on how to determine the water pressure from the height of a tower. Also an article about how to determine the water pressure of a column of water.

This may be too complex of a problem, but it’s certainly worth playing around with.
