PURPOSE: To demonstrate the power of falling water.

DESCRIPTION: The inertia of falling water under pressure may be used to raise a portion of that water above its initial height.

DEMONSTRATION CURRENTLY UNAVAILABLE

Water begins to flow from the funnel through the tube, pushing up the plunger of the lower valve. The rapid flow rate eventually causes the lower valve to close. The pressure backup in the tube raises the plunger in the central bulb, pushing water through the upper tube, where it eventually is raised higher than the initial water level and dumps back into the funnel.

SUGGESTIONS:

REFERENCES: (PIRA 2B60.60) See Demonstration Reference File for further information.

EQUIPMENT: Hydraulic ram with water in tank.

SETUP TIME: 5 min.
