Ported chamber: A barrel chamber with pressure relief ports that allows gas to leak around the cartridge during extraction. Basically the opposite of a fluted chamber as it is intended for the cartridge to stick to the chamber wall making a slight delay of extraction. This requires a welded-on sleeve with an annular groove to contain the pressure.
In other words, the pressure on either end of the liquid (shown in blue in the figure) must be balanced (since the liquid is static), and so P a = P 0 + hgρ. In most liquid-column measurements, the result of the measurement is the height h, expressed typically in mm, cm, or inches. The h is also known as the pressure head. When expressed as a ...
Pressure core sampler: A tool designed to retrieve a sediment core sample while retaining the pressure at depth. [5] Pull past Martin-Decker: Exert extreme tension on stuck pipe, so much so that the pointer needle revolves off-scale beyond the logo of a popular manufacturer of weight indicators, Martin-Decker.

left-to-right: .410 bore, 28 gauge, 20 gauge, and 12 gauge shotgun shells. The six most common shotgun gauges, in descending order of size, are the 10 gauge, 12 gauge, 16 gauge, 20 gauge, 28 gauge, and .410 bore. [7] By far the most popular is the 12 gauge, [7] particularly in the United States. [8]
a cylindrical ring of steel whose inside diameter is finished to gauge tolerance and is used for checking the external diameter of a cylindrical object. Strain gauge: a device used to measure the strain of an object. Thread pitch gauge, also called a threading gauge, pitch gauge, or screw gauge a device used to measure the pitch or lead of ...

An air-pressurized-water fire extinguisher is similar but its water is expelled by the air pressure, it is held by one person, and a flexible hose makes aiming the water stream easy. Handtub A historical fire engine pumped by hand with the water supply held in a tub or cistern on the wagon, the water supply delivered by a bucket brigade.
A sphygmomanometer (/ ˌ s f ɪ ɡ m oʊ m ə ˈ n ɒ m ɪ t ə r / SFIG-moh-mə-NO-mi-tər), also known as a blood pressure monitor, or blood pressure gauge, is a device used to measure blood pressure, composed of an inflatable cuff to collapse and then release the artery under the cuff in a controlled manner, [1] and a mercury or aneroid manometer to measure the pressure.
