The mercury barometer is the oldest type of barometer, having been invented in 1643–44 by the Italian physicist and mathematician Evangelista Torricelli. In its simplest form, it comprises a narrow glass tube closed at one end and open at the other end, which is submerged in a pool of mercury.
This physics video tutorial provides a basic introduction into the mercury barometer. It explains how a basic barometer works. It explains how to calculate the atmospheric pressure of a two...
Feb 15, 2022 · A mercury barometer is an atmospheric pressure measuring instrument based on the displacement of mercury in a glass tube. It is also called the mercury manometer. In short, a mercury barometer is used to measure the pressure exerted by the atmosphere at a given place.
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.
May 6, 2024 · Watch this video to understand very simply, how a mercury barometer works in just 8 minutes! Barometer, device used to measure atmospheric pressure. Because ...
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 · At its core, a mercury barometer operates based on the fundamental principles of fluid mechanics and atmospheric pressure. The device consists of a long glass tube, closed at one end and filled with mercury. The open end of the tube is submerged in a basin of mercury.
Jul 3, 2019 · How the Classic Mercury Barometer Works. The classic mercury barometer is designed as a glass tube about 3 feet high with one end open and the other end sealed. The tube is filled with mercury. This glass tube sits upside down in a container, called the reservoir, which also contains mercury.
The Mercury Barometer. In this document we discuss measuring atmospheric pressure using a Mercury Barometer. This instrument is also known as a Fortin Barometer. This type of instrument was first used by Torricelli in 1643; Fortin slightly modified the original design in 1810.
