Bernoulli Principle

Airflow over an airfoil
Flight is one of the most important achievements of mankind. We owe this achievement to the invention of the airfoil and understanding the physics that allow it to lift enormous weights into the sky.
All flight is the result of forces acting upon the wings of an airplane that allow it to counteract gravity. Contrary to popular belief, the Bernoulli principle is not responsible for most of the lift generated by an airplanes wings. Rather, the lift is created by air being deflected off the wings and transferring an upward force to those wings.
The most important factor in determining the lift generated by an airplane is the angle of attack. The angle of attack is the degree measure from the horizontal that a wing is elevated or declined. When the angle of attack is between 1 and 20 degrees, the most lift is generated. To find the lift generated by a particular area of wing in a standard airfoil shape, a teardrop with the fat end facing forward, the equation L=Cl 1/2 (pV2)S. Cl is the lift coeficent, which is determined by the shape of the airfoil and the angle of attack. P stands for the air mass density, V for the velocity of the air passing over the wing, and S for the area of the wing when viewed from above or below.
As the air flows over the wing producing lift, it grabs onto the wings surface and causes drag. Drag can be measured by the equation D=Cd 1/2 (pV2)S, much like the lift equation. The drag coeficent Cd is found, again, by determining ...

    Ever since I was little I was amazed at the ability for a machine to fly. I have always wanted to explore ideas of flight and be able to actually fly. I think I may have found my childhood fantasy in the world of aeronautical engineering. The object of my paper is to give me more insight on my future career as an aeronautical engineer. This paper was also to give me ideas of the physics of flight and be to apply those physics of flight to compete in a high school competition.

    Have you wondered why airplanes were ever able to fly or how racecars are able to stay on the ground at high speeds? They all use a scientific concept called Bernoulli’s principle, or more commonly known as Bernoulli’s equation. His principle simply states that the faster a fluid flows, the less pressure it applies, the slower the fluid flows, the more pressure it applies.

  • Effects Of Overpopulation In Prisons

    1719 Words  | 4 Pages

    It cost a lot of money to keep one prisoner taken care of with food, medical, and housing. Instead of using that tax money on a prisoner, if that funding were to go to an after school program it would be more beneficiary. More programs for schools lead to children having an activity to do after school instead of getting into some sort of mischief and then getting a criminal record which then produces a vicious cycle of criminal behavior. That criminal cycle will then continue and add to the already overpopulated prison system. The goal here it prevent the blooming of a possible juvenile delinquent into a convicted criminal it before it even starts. So using the tax money that would 've been used on a low level convict who got busted for marijuana lets say, would be used to help prevent future convict to begin with. Not only school programs, but even things that would help improve communities such as parks, job creations, etc. All these things could also help prevent future prisoners because parks are used for activity for children to gather and socialize instead of getting to criminal mischief and job creations are used to prevent being in poverty which is retrospect is one of the main reason people end up in criminal activity. So all in all as you can see, there would be so much benefits in using tax money from a low level convict to the future of our

    First of all you will have to understand the principles of flight. An airplane flies because air moving over and under its surfaces, particularly its wings, travels at different velocities, producing a difference in air pressure, low above the wing and high below it. The low pressure exerts a pulling influence, and the high pressure a pushing influence. The lifting force, usually called lift, depends on the shape, area, and tilt of the wing, and on the speed of the aircraft. The shape of the wing causes the air streaming above and below the wing to travel at different velocities. The greater distance over which the air must travel above the curved upper surface forces that air to move faster to keep pace with the air moving along the flat lower surface. According to Bernoulli’s principle, it is this difference in air velocity that produces the difference in air pressure.

    For a plane to create lift, its wings must create low pressure on top and high pressure on the bottom. However, at the tips of the wings, the high pressure pushes and the low pressure pulls air onto the top of the wing, reducing lift and creating a current flowing to the top. This current remains even after the wing has left the area, producing really awesome vortices.

    Persons are usually penalized for plagiarism in their academic setting. In most universities a person will receive an F for the class without refund. Sometimes the person may face monetary fines and will be banned from extracurricular activities (“Plagiarism Q&A”). The College of New Jersey has little tolerance for those who plagiarize. If a student is caught plagiarizing, the faculty member will first decide whether or not the student’s violations were intentional.

  • Flight of the Frisbee

    1460 Words  | 3 Pages

    Objects that fly are designed to push air down. The momentum of the air going down is what causes Frisbees or winged objects to travel skyward. This type of force acting on a flying disk is typically known as the “aerodynamic lift” (Bloomfield, 1999, p. 132). Consider a flying kite, which in essence is also a winged object. When a kite’s flat bottom surfaces are angled into the wind, air gets pushed down and the kite glides upward. Kites must rely on the wind to keep it suspended in mid-air, while flying birds and insects utilize their muscular flapping motions to maintain their flight in motion. Airplanes rely on spinning propellers and turbine fans to provide adequate momentum for take off from the runway. With flying Frisbees, that momentum is generated primarily by the tossing power of the human arm and wrist motion. The Frisbee’s course of flight is “directly related to the torque or twist force” applied by the individual throwing the flying disk (Fisher & Phillips, 2003, p. 12).

    Plagiarism is a severe problem because it has since become an epidemic and is being practiced at an alarmingly increasing rate. It has become widely accepted among students at many colleges and universities across the United States. It has gotten to the point that many students don’t even consider it cheating. This fact alone makes it even more serious and harder to control. It is now common practice to obtain someone else’s writing and turn it in as an original work. It is not difficult to purchase a pre-written paper or hire another individual to write a paper. Students are willing to pay whatever the cost so that they don’t have to do the work themselves. In fact, paper-selling services such as this have become quite a lucrative business. With the age of technology quickly advancing it has become all the more easily to plagiarize.

    Evaluated more thoroughly, these statistics show not only a problem with student plagiarizing, but also an underlying problem of the failure to recognize it as a severe threat to the future development of today’s society. In order for society to continue to grow and prosper in technology, educators and employers alike must realize that plagiarism is indeed a genuine concern and as a result, must be dealt with in a more severe matter to encourage individualism. Often the threat of a failed grade or expulsion from a university is not enough to deter students from cheating if known instances have not been appropriately dealt with in the past. If the problem is to be mended, educators must make examples of students who plagiarize written material, so we can discontinue the trend that seems to be irresistible to today’s society.
