Online Experiment: Fluid Pressure and Flow
Bernoulli discovered that a part of the pressure energy is converted into kinetic energy.
When velocity increases it therefore results in a drop in pressure, so that the lowest pressure occurs in the narrowest cross-section. Bernoulli’s equation states that the energy of a frictionlessly flowing, incompressible fluid is constant.
With the help of this program you can see for yourself how a Bernoulli experiment works.
Description
Explore pressure in the atmosphere and underwater. Reshape a pipe to see how it changes fluid flow speed. Experiment with a leaky water tower to see how the height and water level determine the water trajectory.
Sample Learning Goals
Investigate how pressure changes in air and water.
Discover how you can change pressure.
Predict pressure in a variety of situations.
Determine how fluid motion affects the pressure.
Figure out how to convert water pressure to water velocity.
