33pressure gauge — 1. an instrument for measuring the pressure of a gas or liquid. 2. an instrument used to determine the pressure in the bore or chamber of a gun when the charge explodes. [1860 65] * * * Instrument for measuring the condition of a fluid (liquid or …
34fluid — fluidal, adj. fluidly, fluidally, adv. fluidness, n. /flooh id/, n. 1. a substance, as a liquid or gas, that is capable of flowing and that changes its shape at a steady rate when acted upon by a force tending to change its shape. adj. 2.… …
35Pressure drop — For other uses, see Pressure Drop (disambiguation). Pressure drop is a term used to describe the decrease in pressure from one point in a pipe or tube to another point downstream. Pressure drop is the result of frictional forces on the fluid as… …
36Pressure point — For other uses, see Pressure point (disambiguation). Pressure point (穴位) Chinese name Chinese 穴位 …
37Pressure gradient — In atmospheric sciences (meteorology, climatology and related fields), the pressure gradient (typically of air, more generally of any fluid) is a physical quantity that describes in which direction and at what rate the pressure changes the most… …
38Fluid — A fluid is defined as a substance that continually deforms (flows) under an applied shear stress. All liquids and all gases are fluids. Fluids are a subset of the phases of matter and include liquids, gases, plasmas and, to some extent, plastic… …
39fluid pressure — Physics, Mech. the pressure exerted by a fluid, directly proportional to the specific gravity at any point and to the height of the fluid above the point. [1835 45] * * * fluid pressure, the pressure exerted by a confined fluid in static… …
40pressure regulator — A device that reduces the pressure of the fluid from a high value to a lower value and, thereafter, maintains a constant output. The out pressure of the regulator can be adjusted. This is achieved by bypassing a portion of the fluid back to the… …
