Two identical wooden barrels are fitted with long pipes extending out their tops. The pipe on the first barrell is 1 foot in diameter, an the pipe on the second barrell is only 1/2 inch in diameter. When the larger ptpe is fill with water to a height of 20 feet, the barrell bursts. To burst the second barrell. will water have to be added to an height less than, equal too, or greater than 20 feet? Explain.
Thank you.

  1. same height
    pressure = density * g * height

  2. Same height (20 feet). The pressure in the barrel depends only upon the height of the column of water above.
