PLEASE REQUEST DEMOS WELL IN ADVANCE

Due to Physics Building renovations, the lead time to set up demo requests has increased due to the need to transport equipment across campus. Please be kind and let me know well ahead of time what you need.

Hydrostatic Pressure dependence on depth

Purpose:

To show that the pressure increases with depth below the liquid level.

Procedure:

The small disc is held onto the bottom end of one of the vases by the string and then lowered into a large jar of water. The pressure holds the disc in place. Then water is added from the top until the disc is free. Repeat the process with the other vases and note the level at which the added water frees the disc.

Equipment:

Constant Level Tubes
