Bernoulli's Equation: Interactive Simulations

These simulations are browser-based and will work directly on this page. Try to predict the behavior when a parameter changes before using a slider to change that parameter. Screencasts below explain how to use these simulations.

Bernoulli Equation for Pipe Flow

Try to answer these questions before determining the answer with the simulation. We suggest that you write down the reasons for your answers.

  1. It is possible for the outlet pressure to be higher than the inlet pressure for liquid flow through a pipe system? Why?
  2. For liquid flow through a pipe whose outlet is higher than the inlet and whose diameter is half the inlet diameter, how does the outlet velocity compare to the inlet velocity? Why?
Measuring Flow Rates with a Pitot Tube

Try to answer these questions before determining the answer with the simulation. We suggest that you write down the reasons for your answers.

  1. As the velocity increases for fluid flowing in a pipe, how does the height of fluid in a pitot tube change? Why?
