ejectie

Ejectie is a noun used in several languages to describe the act of ejecting, expelling, or discharging something from a system, container, or body. The term derives from Latin ejectio, from eicere meaning to throw out. Its exact meaning and usage vary by language and field.

In engineering and physics, ejectie commonly refers to devices and processes that generate movement or suction by using a high-velocity jet of one fluid to entrain another. Steam ejectors, gas ejectors, and ejector pumps use jet action to create vacuum, transfer energy, or mix fluids without moving parts. Such devices are employed in chemical processing, power plants, and vacuum systems.

In aerospace and transportation, the term appears in relation to safety and propulsion concepts. An ejection seat, for example, is a system designed to rapidly remove an occupant from an aircraft in an emergency. Ejectie-related technology can also describe components that expel gases or materials as part of a propulsion or cooling mechanism.

In other contexts, ejectie can be used more generally to denote discharge or expulsion of substances from containers, chambers, or biological systems. In medicine and biology, precise terminology is typically preferred, and the specific word for a given discharge varies by language and specialty.
