Today I will… Review how fluid pressure is related to the

motion of a fluid, as well as, Describe some applications of Bernoulli’s Principle

BERNOULLI’S PRINCIPLE

The faster a fluid moves the less pressure the fluid exerts

As the speed of the moving fluid increases the pressure within the fluid decreases.

How does Bernoulli’s Principle explain the behavior of the paper from the activity?

Because the air above the paper moves and the air below the paper does not- moving air exerts less pressure then still air- Resulting in the still air exerting more pressure at the bottom of the paper-pushing it up.

OBSERVE FIG. 17 ON PG. 96 IN TEXTBOOK

*Is the fluid between the cans moving more quickly or more slowly than the air on the opposite sides of the cans? -More Quickly*How does the movement of air between the cans affect the pressure between the cans?-As the speed of the air increases, the pressure decreases.

BERNOULLI’S PRINCIPLE IS A FACTOR THAT HELPS EXPLAIN –HOW PLANES FLY..

Lift: is an upward force

•If the air moves faster above the object, fluid pressure pushes the object upward

•If the air moves faster below the object, fluid pressure pushes it downward.

BERNOULLI’S PRINCIPLE IS A FACTOR THAT HELPS EXPLAIN –HOW PLANES FLY..

-The curved shape of the wing provides lift. The curved shape allows air to move faster over the top of the wing then the bottom exerting less pressure than the air below- creating lift-The wings are designed to produce lift. The slant - Air that hits this slant is forced downward- which helps to push the plane upward during take off

BERNOULLI’S PRINCIPLE IS A FACTOR THAT HELPS EXPLAIN –HOW AN ATOMIZER WORKS…

BERNOULLI’S PRINCIPLE IS A FACTOR THAT HELPS EXPLAIN- WHY SMOKE RISES UP A CHIMNEY

BERNOULLI’S PRINCIPLE IS A FACTOR THAT HELPS EXPLAIN –HOW A FLYING DISK GLIDES…

The faster moving air following the disks curved upper surface exerts less pressure than the slower- moving air beneath it. -Tilting it towards you when you throw it will keep it in the air longer… The spinning motion keeps it stable as it glides

LABEL THE PRESSURE AND SPEED OF THE AIR
