State Bernoulli's theorem. Explain the lift of an airfoil using the theorem. |

Answer» TheBernoulli equation statesthat an increaseinvelocity leads to an decreaseinpressure. Thus the higher the velocity of the flow, the lower the pressure An airfoil is referred to any device that reacts to air moving over its surface. A wing is an example of such a device. In its simplest form, Bernoulli equation states that at a point where the speed of a fluid ( liquid or gas) decreases, the pressure of the fluid at that point increases. Probably on of the most famous applications of this equation applies to describing and formulating the the lifting of an airplane wing. A wing is designed and shaped in a way that the speed of air flowing over its top surface increases, while the speed at the lower part decreases. According to the Bernoulli’s equation, the pressure on the top surface decreases while the pressure on the low surface increases and as a result there is an upward pressure or force on the wing causing it to go up.
