Purpose: Illustrate the Venturi effect in 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 meters.
