Bernoulli’s Principle for Flight

Learn how Bernoulli's Principle explains the relationship between pressure and speed in fluid flow, crucial for understanding lift in aviation. See how it affects the flight of birds and planes, where low pressure beneath the wing creates lift for aerial navigation.

  1. Bernoulli’s Principle חוקברנולי

  2. Bernoulli’s Principle: • מדען שוויצרי הידוע בעיקר בזכות עבודתו הקושרת בין הלחץ בזורם ומהירותו

  3. Bernoulli’s Principle • Pressure in a moving stream exerts less pressure than the air surrounding the moving stream Quick stream = low air pressure Slow stream = High air pressure

  4. Bernoulli & Flight • Bernoulli’s Principle is what allows birds and planes to fly. • The secret behind flight is ‘under the wings.’

  5. The air on top of the wing must travel a longer • distance than the air below the wing. But, air on • both sides must reach the end of the wing at the • same time. Therefore, the air on top of the wing • traveling faster = less air pressure. Creates Lift AIR

  6. Below is a NASA illustration of what surface pressure is exerted on what surface areas of the wing.
