👉 In physics and engineering, a manometer is a device used to measure pressure. It consists of two tubes of different diameters that are connected by a tube of negligible diameter. The length of the tube with larger diameter is longer than the other one, which causes the fluid to flow more easily between them. When a gas or liquid enters the manometer, it creates a pressure gradient. This pressure gradient can be measured using a device called a manometer. The pressure at any point in the man
