Venturi Tube With Manometers
Purpose
To illustrate the venturi effect.
Equipment
Venturi tube with connected manometers, blower.
Images
Description
Turn on the blower and slowly move it so that it directs some air into the venturi tube device. The higher water level indicates less air pressure in that tube. Start it slowly; a sudden burst of air can blow out the water. In the picture both the venturi effect and the loss of pressure due to viscous effects can be seen.
