What happens here

The video opens with a demonstration using a tall PVC pipe filled with water. A cordless drill is used to create holes at various depths along the pipe. The water streams forcefully from the lower holes and less so from the upper holes, visually demonstrating that hydrostatic pressure increases with depth.

Goal: Visually illustrate the principle that water pressure increases with depth.

Tools and materials

  • Cordless drill DeWalt — Drilling holes in the PVC pipe for water to exit
  • PVC pipe — Simulating a water column to demonstrate pressure differences
  • Water N/A — Filling the PVC pipe for the demonstration

What they say

Hide

This is your standard foundation. This gets poured in two sections. You have a footing and a stem wall. Because of hydrostatic pressure, there are some steps that have to be taken. Hydrostatic pressure will be low up here and high down here. The lowest one has the most pressure and as the water column comes down, it still stays that way. Because this pressure increases at the bottom, these braces hold the top from horizontal movement
