DHS02 - Pascal's Vases

Objective:

To demonstrate that the pressure at the bottom of a vessel is proportional to the depth of the liquid and is independent of the volume and shape of the vessel.

 
Apparatus:  
  • Pascal's Vase Apparatus
  • Water, colored



Method:

Each of the three different shaped glass vases are interchanged. In each case the colored water is adjusted to the water — level indicator by moving the water reservoir up or down. The pressure gauge for all these experiments will read the same value.
