mercury barometer, device used to measure atmospheric pressure with a column of mercury. The mercury barometer is the oldest type of barometer, having been invented in 1643–44 by the Italian physicist and mathematician Evangelista Torricelli.
A mercury barometer is an instrument used to measure atmospheric pressure in a certain location and has a vertical glass tube closed at the top sitting in an open mercury-filled basin at the bottom. Mercury in the tube adjusts until the weight of it balances the atmospheric force exerted on the reservoir.
Mercury Barometer. This is the most commonly used barometer. Torricelli invented this in the year 1643. It consists of a glass column with mercury and inches markings on it. The top end of the tube is closed, and the bottom end is rested in a cup containing mercury known as a cistern.
A mercury pressure gauge is a type of manometer using mercury as the working fluid. The most basic form of this instrument is a U-shaped glass tube filled with mercury. More complex versions deal with very high pressure or have better means of filling with mercury. Description. The instrument consists of a glass U-tube half-filled with mercury.
Oct 24, 2023 · Mercury Barometer The mercury barometer is the oldest type of barometer, invented by the Italian physicist Evangelista Torricelli in 1643. Torricelli conducted his first barometric experiments using a tube of water.
Jul 3, 2022 · The simplest kind of barometer is a tall closed tube standing upside down in a bath of mercury (a dense liquid metal at room temperature) so the liquid rises partly up the tube a bit like it does in a thermometer. We use mercury in barometers because it's more convenient than using water.
Mar 19, 2024 · Mercury barometers have long been an essential tool in meteorology, providing accurate measurements of atmospheric pressure. Developed in the 17th century by Italian physicist Evangelista Torricelli, this ingenious instrument revolutionized our understanding of atmospheric pressure and weather forecasting.
