slug

Physics

An f.p.s. unit of mass equal to the mass that will acquire an acceleration of 1 ft sec⁻² when acted on by a force of 1 pound-force.

Science and Technology

A terrestrial, air-breathing, gastropod mollusc that lacks a visible shell, or that carries a shell too small for the animal to withdraw into it. Most slugs have two pairs of retractable tentacles, the upper pair sensitive to light and the lower pair to scent, and behind the head a saddle-like mantle with a respiratory opening; the hind part of the mantle forms a lung. The underside is a muscular foot. The entire body is coated in mucus that prevents desiccation. Most slugs feed on decaying plant material and fungi, some on carrion, and some are predators. Some are serious crop pests. There are about 5000 species found worldwide.

1. A moving bullet-shaped gas pocket formed in multiphase fluid flow. In a vertical pipe or tube the slug is axially symmetrical and occupies most of the cross-sectional area of a pipe. In horizontal flow, the shape of the pocket has a curved nose and the shape is governed by buoyancy, ratio of gas to liquid, and their relative velocities.

2. A unit of mass in the f.p.s. engineering system of units that will accelerate at one foot per second per second to give a one pound (lb) force.
