Bernoulli's Principle Animation

Interactive animation shows how pressure and velocity in a fluid behave according to Bernoulli's Principle.
Pressure, and it is directed downstream. The static pressure decreases when the speed increases, as explained in the Background Theory section above. This explains why the water stream coming out of a firefighter& ,s hose gets narrower a short distance past the nozzle - the stronger atmospheric pressure overwhelms the weaker static pressure in the quickly flowing water and compresses the water stream. At the bottom of a swimming pool, the force on your body is from the static pressure of the
