![]() ![]() This difference of pressure is helpful in giving a vertical lift to the plane. Consequently the pressure above the surface of the wing is less as compared to the lower surface of the wing. Due to this shape of the wing, the air currents at the top have a large velocity than at the bottom. The upper surface is made convex and the lower surface is made concave. Wings of Aeroplane Wings of an aeroplane are made tapering. Bernoulli’s principle is used in an atomiser and filter pump. This ppt is a investigatory project of physics for class 11th and 12th for any board. I owe a deep sense of gratitude to my physics. ![]() ![]() Electrostatics part 2 chapter notes, class 12 physics class 12 notes edurev is made by best teachers of class 12.Cbse class 12 physics chapter 14 electronic devices notes in pdf are available for free download in mycbseguide mobile app. It is used in a carburettor to mix air and petrol vapour in an internal combustion engine. Physics Investigatory Project Class 11 For Free Download In. Venturimeter, atomiser and filter pump Bernoulli’s principle is used in venturimeter to find the rate of flow of a liquid. Many people find this situation paradoxical when they first encounter it (higher velocity, lower pressure). Bernoulli's law states that if a non-viscous fluid is flowing along a pipe of varying cross section, then the pressure is lower at constrictions where the velocity is higher, and the pressure is higher where the pipe opens out and the fluid stagnate. ![]()
