Unstable; volatile; colorless; extremely poisonous; gas or liquid; HCN;
soluble in water, in alcohol, and in ether; only slightly dissociated with
water; and an odor resembling that of bitter almonds. Formed by
decomposing metallic cyanides with hydrochloric acid.
Syn:hydrogen cyanide; prussic acid.
Standard, 2; Handbook of Chemistry and Physics, 2
A cyclone separator in which a spray of water is used. ASM, 1
Computer codes or models that compute the properties or predicted behavior
of explosives or materials subjected to supersonic (dynamic) forces.
The aspect of hydromechanics that deals with forces that produce motion.
CF:hydrostatics
An obsolete term for a type of surface wave that is similar to a Rayleigh
wave but has an opposite particle motion. Syn:H wave
An instrument for determining the velocity of a fluid in motion by its
pressure. Standard, 2

See:chalcophanite
A member of the garnet group having SiO4 partly replaced by (OH)
4 . CF:hydrogrossular; garnetoid.
See:hydrocyanic acid
A condition of low ductility in metals resulting from the absorption of
hydrogen. ASM, 1
The stripped (naked) proton of hydrogen, H+, or the proton combined with
one or more molecules of water, as H3 O+ or H(H2 O)
+ . The latter is sometimes called oxonium, hydroxonium, or
hydronium ion. H+ is usually spoken of as the proton. H-ion concentration
is the pH value. Pryor, 3
a. Said of coals high in moisture, such as brown coals. AGI
b. Said of coals high in volatiles, such as sapropelic coals. AGI
Colorless; flammable; gas; H2 S . It is readily decomposed. Reacts
with bases forming sulfides and with some metals to produce metal sulfides
and to liberate hydrogen. Poisonous. Syn:hydrosulfuric acid
Handbook of Chemistry and Physics, 2
Prospecting guided by the composition of ground or surface water.
Syn:hydrochemical prospecting
A graph showing stage, flow, velocity, or other characteristics of water
with respect to time. A stream hydrograph commonly shows rate of flow; a
ground-water hydrograph, water level or head. AGI
a. The science that deals with the physical aspects of all waters on the
Earth's surface, esp. the compilation of navigational charts of bodies of
water. AGI
b. The body of facts encompassed by hydrography. AGI
