Product Information

This is a clear and simple way to demonstrate Bernoulli’s Law to your students.
The Venturi tube is found in everything from carburators to aircraft airspeed indicators. This demonstration version is made of glass and has three side tubes for attaching an included three-leg manometer.
The manometer is filled with colored water to show the relative pressures at significant points of the tube when gas is flowing through it.
By blowing through the tube, a sufficient gas flow can produce clear differences of water level in the three manometer legs. The tube is 22 cm long, 2.0 cm in diameter at the wide ends, and narrows to 10 cm in diameter in the middle.
