Homework Help: Pascal's principle

  1. Jan 4, 2010 #1
    I can't seem to wrap my ahead around this question! Please help me understand.

    A water dispenser for pets has an inverted plastic bottle. When a certain amount of water is drunk from the bowl, more water flows automatically from the bottle into the bowl. The bowl never overflows. Explain the operation of the dispenser. Does the height of the water in the bottle depend on the surface area of the water in the bowl?

    here goes!!!

    I am thinking if a given volume of water is taken away then the height of the water in the bottle would be more for smaller surface area of the water in the bowl. This is so confusing just trying to put it into words! I am so confused!
