A jet is a stream of fluid that is projected into a surrounding medium, usually from some kind of a nozzle, aperture or orifice.[1] Jets can travel long distances[quantify] without dissipating.
Jet fluid has higher speed compared to the surrounding fluid medium. In the case that the surrounding medium is assumed to be made up of the same fluid as the jet, and this fluid has viscosity, some of the surrounding fluid is carried along with the jet in a process called entrainment.[2]
Some animals, notably cephalopods, move by jet propulsion, as do rocket engines and jet engines.
