This difference of pressure is helpful in giving a vertical lift to the plane.Physics Projects : Physics Projects Physics Project Report Topics, Physics Project Ideas, Physics Project experiments, Projects on Physics, Class IX, X, XI.Class 12 physics electrostatics get here the notes for class 12 physics electrostatics. 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.
It is used in a carburettor to mix air and petrol vapour in an internal combustion engine. 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.
