Water Nozzle



The Water Nozzle

Water Nozzle Experiment

Water replaces air in these experiments. The results are even more pronounced, since water is less compressible than air. The force upon a plate with a surface area of a few square inches, fed with normal domestic water pressure can be in the tens of pounds. In addition, a small white ring, indicating cavitation, often appears around the input orifice.  As with the air, all channel patterns adhere except ones that entrain parallel, non expanding flow.


The hourglass configuration. Note the test plate coming into position.

Radial Momentum (fanning out of the water) induces a reduction in density, hence a drop in pressure and the bottom plate sticks to the top plate.

An hourglass-shaped disk sticks while a corridor-shaped disk does not.
