![]() ![]() ![]() ![]() 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. Gravitatio n Submitted by :-Name - (Your Name) Class - XI (Grade) Roll no. 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 Aero plane Wings of an aero plane are made tapering. Bernoulli’s principle is used in an atomizer and filter pump. Tuesday, NovemINVESTIGATORY PROJECTS - CLASS XII ( PHYSICS ) WITH THE LINK, YOU CAN DOWNLOAD THE LINKS OF INVESTIGATORY PROJECTS FOR CLASS XII - PHYSICS. It is used in a carburetor to mix air and petrol vapor in an internal combustion engine. Venturi-meter, atomizer and filter pump Bernoulli’s principle is used in venturi-meter 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.
