Bernoulli's Effect in Tube of Changing Diameter

The tube of changing diameter rests next to a box of ping pong ballls

Concept Overview:

1. Bernoulli's Effect

2. Venturi Effect

Lecturer Procedure

Step(s) to Follow	Expected Result
1. Connect apparatus to air output beneath lecture bench. 2. Place ping pong balls directly into the streams of air from the tube.	Ping pong balls will have different heights, corresponding to the different diameters of tube (see below)

Expected Result

1. Connect apparatus to air output beneath lecture bench.

2. Place ping pong balls directly into the streams of air from the tube.

Ping pong balls will have different heights, corresponding to the different diameters of tube

(see below)

The tube in action shows balls suspended at different heights depending on the diameter of the tube
