Air Lock -

An is a device or physical phenomenon involving trapped air that regulates passage between different pressures or blocks the flow of liquids . Depending on the field—whether aerospace, plumbing, or medicine—an "air lock" serves very different purposes. 1. Pressure Regulation (Engineering & Aerospace)

An air lock (or vapor lock) occurs when gas becomes trapped in a high point of a liquid-filled pipe system, partially or completely blocking the flow . air lock

: Historically used in underwater tunnels and bridge foundations (caissons) to transition workers from atmospheric pressure to high-pressure work zones. An is a device or physical phenomenon involving

: It can lead to sputtering faucets, no water flow in gravity-fed systems, or the failure of pumps that rely on liquid for lubrication. Pressure Regulation (Engineering & Aerospace) An air lock

In engineering, an air lock is a chamber that allows people or objects to pass between areas of different air pressures without significantly changing the pressure of either environment.

: Air can enter a system during maintenance, pump restarts, or through dissolution in the liquid itself. air lock - Students | Britannica Kids | Homework Help
