Bernoullis Principle

CHAPTER 1 INTRODUCTION: Bernoullis 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. writing help service 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 aircrafts rolling motion and balance. * Thursday 2 June-06-011 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 dont 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 * Morgan County students compete at wind generator contest at GCSU related news 2011-05-12 Hard work paid off for 8th grade students at Morgan County Middle School as their teams placed second and third in the 1st Annual Middle Grades Wind Power Competition at Georgia College and State University today, Monday, May 9, 2011. The competition was supported by a grant from the National Science Foundation, and highlighted Science, Technology, Mathematics, and Engineering (STEM) Education. * How cats drink: A lesson in fluid mechanics related news 2010-11-12 Philadelphia Daily News By Tom Avril Inquirer Staff Writer In the annals of animals who have contributed to science, there are Laika the Soviet space dog; Koko, the gorilla who is said to use sign language; and Lancelot, the blind dog who regained some vision after gene therapy at the University of Pennsylvania. And now, Cutta Cutta, the cat?

A million pounds of metal traveling at more than 200 mph, countering the force of gravity. Its a minor miracle. Which is why it is so shocking when planes fall from the sky, as happened Chapter II: RELATED STUDIES: *Archimedes principle (Hydrostatics) Archimedes principle that states that a body immersed in a fluid is buoyed up by a force equal to the weight of the displaced fluid. The principle applies to both floating and submerged bodies and to all fluids, i. e. , liquids and gases. It explains not only the buoyancy of ships and other vessels in water but also the rise of a balloon in the air and the apparent loss of weight of objects underwater *Hydrodynamics A liquid or gas flows from regions of high pressure to regions of low pressure. This happens, for example, when water is squeezed from a sponge or squirted from a hose. The flow of a liquid or gas can be laminar (smooth) or turbulent (rough and eddying). *Torricellis Theorem Is an application of the Law of Falling Bodies to liquids. This theorem was derived by the Italian physicist Evangelista Torricelli (1608-1647). It states that a liquid flowing from an outlet in a tank has the same speed as an object falling freely from the level of the liquids surface to the level of the outlet. The theorem also states that a jet of water rises to the level of its source, unless opposed by friction. Torricellis Theorem explains the action of an artesian well. *Pascals Law, The law states that pressure upon the fluid at any point will be transmitted uniformly throughout the fluid. In the case of a gas, a pressure increase causes compression (uniform lessening of volume). Liquids, however, are not compressible. An increase of pressure at any point upon a contained liquid will result in an increase of pressure at every point upon the walls of the container; the volume of the liquid remains the same. Pascals Law explains the action of a hydraulic press and similar devices. Aerodynamics Aerodynamics is the study of air flow over airplanes, cars, and other objects. Airplanes fly because of the way in which air flows over their wings and around their bodies, so a knowledge of aerodynamics is crucial to the design and construction of airplanes. The efficiency with which automobiles use fuel is also a function of air flow. Even stationary objects are affected by aerodynamics. Winds blowing past a tall building, for example, may cause windows to pop out if they are not properly designed and installed. RELATED LETERATURE: *Hydrodynamica By Daniel Bernoulli He considered the properties of basic importance in fluid flow, particularly pressure, density, and velocity, and set forth their fundamental relationship. He put forward what is called Bernoulli’s principle, which states that the pressure in a fluid decreases as its velocity increases. He also established the basis *Liquids and Gases: Principles of Fluid Mechanics Book by Paul Fleisher; Lerner, 2002 Subjects: Fluid MechanicsJuvenile Literature Bernoulli’s principle works just as well with liquids.

So the side tube generates *Principles of Experimental Phonetics Book by Norman J.

Related books and magazines as the primary tool of the study were used. Books and information from internet were also used as the other sources of additional knowledge about the principle of Bernoulli’s, we also asked some physics teacher about the matter that we have.
