  • Principles of Flight: Bernoulli's Principle

    2016-10-28 · Air pressure Air foil Bernoulli Principle Fluid Force Gravity Lift 5. Explain that the Bernoulli Principle states that slower moving fluids create greater pressure (force) than faster moving fluids. Tell the students that air is a fluid because it flows and can change its shape. Inflate balloons of different sizes and shapes to make

    A Venturi [ Figure 3] demonstrates Bernoulli's principle: A 1 V 1 P 1 = A 2 V 2 P 2. A = Area, V = Velocity, and P = Pressure. Assuming area is constant, you get: V 1 P 1 = V 2 P 2. The formula shows that as the velocity of fluid (air) increases, its pressure must decrease.

  • BASIC PRINCIPLES OF MONITORING AND EVALUATION

    2005-3-9 · A propeller accelerates a large volume of air by a small amount, whereas a jet engine accelerates a small volume of air by a large amount. This can be understood by Newton's 2nd law of motion which is summarized by the equation F=ma (force = mass x acceleration). Basically the force or thrust (F) is created by accelerating the mass of air (m ...

    2009-7-17 · The basic 4 steps for any internal combustion engine are: 1) Intake of air (and possibly fuel). 2) Compression of the air (and possibly fuel). 3) Combustion, where fuel is injected (if it was not drawn in with the intake air) and burned to convert the stored energy. 4) Expansion and exhaust, where the converted energy is put to use.
