DHS01 Water Pressure Varies with Depth

Objective:

– To show variation of water pressure with depth. Shows that water pressure is the same in all directions at any particular level.

Apparatus:

    • Large beaker, 1.8L
    • Manometer and funnel
    • Stand, clamp, Tygon tubing

DHS01 - Variation of Water Pressure with Depth

Method A:

The funnel (open-end down) is lowered slowly into the water to show that pressure varies directly as depth. The funnel may then be turned sideways to show that the pressure at that depth is the same in all directions.

The bulb of the funnel may be filled with water and the funnel raised so that the water level in the funnel is above that in the beaker. A partial vacuum is thus formed, as is indicated by the manometer.
