Torricelli's Tank
Purpose
A vertical cylinder with holes at different heights demonstrates that water pressure increases with depth. Students observe that the horizontal range of water jets increases for lower holes, providing visual evidence for Torricelli's theorem (\(v = \sqrt{2gh}\)).
Figure 1:
Torricelli's tank in operation. Water jets from lower holes travel farther, showing that exit velocity increases with depth below the surface.
