1. 1. BASIC PRINCIPLES OF AERODYNAMICS
2. 2. OUTLINE  INTRODUCTION  DEFINITIONS  BERNOULLI´S PRINCIPLE  VENTURI EFFECT  APPLICATIONS  BIBLIOGRAPHY
3. 3.  Aerodynamics is a branch of dynamics concerned with the study of the motion of air.  In 1726, Isaac Newton became one of the first aerodynamicists in the modern sense when he developed a theory of air resistance, which was later verified for low flow speeds.
4. 4. Daniel Bernoulli proved experimentally that "the internal pressure of a fluid (liquid or gas) decreases as the fluid velocity increases" . Bernoulii’s Principle
5. 5. VENTURI EFFECT Phenomenon in which a moving fluid inside a closed conduit decreases its pressure when the velocity increases when passing through a zone of smaller section.
6. 6. Principle of conversation of energy when if Pressure decrease the speed increase or viceversa
7. 7. Formula 𝑝1 − 𝑝2 = 𝜌 2 𝑣2 2 − 𝑣1 2
8. 8. Different Applications for Venturi Tubes  Important air is considered like a fluid.  It can be used to calculate the flow rate from these measured pressure differences
9. 9. Basic Carburetor • Substances outside of the Venturi tube are sucked into the low-pressure area • Different pressure produce that basic carburetor work.
