Bernoulli's Principle
CHAPTER 1
INTRODUCTION:
Bernoulli's Principle is a physical phenomenon that was named after the Swiss scientist Daniel Bernoulli who lived during the eighteenth century. Bernoulli studied the relationship of the speed of a fluid and pressure.
The Swiss mathematician and physicist Daniel Bernoulli (1700-1782) discovered the principle that bears his name while conducting experiments concerning an even more fundamental concept: the conservation of energy. This is a law of physics that holds that a system isolated from all outside factors maintains the same total amount of energy, though energy transformations from one form to another take place.
The principle states that "the pressure of a fluid [liquid or gas] decreases as the speed of the fluid increases." Within the same fluid (air in the example of aircraft moving through air), high-speed flow is associated with low pressure, and low-speed flow is associated with high pressure.
OBJECTIVE:
*USE BERNOULLI’S PRINCIPLE TO EXPLAIN HOW THE ENERGY OF A FLUID AND ITS PRESSSURE ARE RELATED.
*EXPLAIN SOME SITUATIONS USING BERNOULLI’S PRINCIPLE.
SCOPE:
*the first fly of airplane
In 1899, after Wilbur Wright had written a letter of request to the Smithsonian Institution for information about flight experiments, the Wright Brothers designed their first aircraft: a small, biplane glider flown as a kite to test their solution for controlling the craft by wing warping. Wing warping is a method of arching the wingtips slightly to control the aircraft's rolling motion and balance.

VORTEX CLIMBER: Researchers at the University of Canterbury can make a robot stick to walls through pressurized air. The non-contact adhesive pad, or air gripper, uses the Bernoulli principle. The feet of the robot don't actually touch the wall but are held 25 micrometers away - about 0.025 mm. Air is squirted out from the feet sideways at high speed, causing a low pressure vortex that creates a...
