  1. Applying Bernoulli’s Principle Section 4 -- Chapter 3

  2. Bernoulli’s Principle • Named after Swiss Scientist Daniel Bernoulli • He found that the faster the fluid moves the less pressure the fluid exerts. • Principle states that the pressure exerted by a moving stream of fluid is less than the pressure of the surrounding fluid.

  3. Bernoulli’s Principle • Bernoulli’s principle explains flight from a small kite to a huge airplane. • Objects are designed so that their shapes cause air to move at different speeds above and below them. • If the air moves faster above the object, pressure pushes the object upward. • But if air moves faster below the object, pressure pushes it downward.

  4. Bernoulli’s Principle at Home • Wind blowing across the top of a chimney lowers the air pressure, therefore the higher air pressure at the bottom pushes the air and smoke up the chimney. • The attack of the shower curtain can also be explained by Bernoulli’s Principle. How you ask?
