PURPOSE: To illustrate the venturi effect in a water.
DESCRIPTION: The apparatus consists of a water reservoir, a pump, and a venturi tube with pressure gauges. When the pump is activated and air removed from the system, the water circulates around a closed path. The pressure is measured at four points along the tube.
This is a sensitive experiment; the pressure differences here are rather small. It is important to remove all air from the system and to install a semi-flexible reservoir along the tube to absorb the shock from the pump and reduce vibration of the met ers.
SUGGESTIONS: This one is hard to see, because of the small gauges and the small pressure differences.

EQUIPMENT: Venturi tube apparatus with gauges, water pump, and shock absorber reservoir.
SETUP TIME: 10 min.
