Bernoulli's Principle

In the Bernoulli's Principle Concept Builder, learners combine the use of Bernoulli's principle and the principle of continuity in order to analyze a variety of fluid flow phenomenon. There are 38 total questions that are organized into 16 different Question Groups and spread across three Activities. The three activities include Bernoulli Effects, Pressure Meters, and Bernoulli Thinking. Activity 1 - Bernoulli Effects provides six common examples of the Bernoulli effect (airplane wing, spinning golf ball, spinning baseball, etc.) and requires that students use Bernoulli's principle to determine where the pressure is greatest and the effect that this has upon the object. In Activity 2 - Pressure Meters, learners are presented a diagram of a horizontal flow tube that narrows or widens; they must identify the location with the greatest speed and the location with the greatest pressure. They then match their conclusions to what an attached Venturi meter or manometer would look like. And in Activity 3 - Bernoulli Thinking, learners use Bernoulli's equation (and the continuity equation) to compare the velocity, height, and pressure at two locations along an ascending or descending flow tube. Question-specific help is provided for each of the 16 situations. Use of this Concept Builder with our Task Tracker system allows teachers to track student progress.
