Online Experiment: Fluid Pressure and Flow


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.
