ATOMIC ABSORPTION SPECTROSCOPY

Measures the radiation absorbed by chemically unbound atoms by analyzing the transmitted energy relative to the incident energy at each frequency. The procedure consists of diluting the fluid sample with methyl isobutyl ketone (MIBK) and directly aspirating the solution. The actual process of atomization involves reducing the solution to a fine spray, dissolving it, and finally vaporizing it with a flame. The vaporization of the metal particles depends upon their time in the flame, the flame temperature, and the composition of the flame gas. The spectrum occurs because atoms in the vapor state can absorb radiation at certain well-defined characteristic wave lengths. The wave length bands absorbed are very narrow and differ for each element. In addition, the absorption of radiant energy by electronic transitions from ground to excited state is essentially and absolute measure of the number of atoms in the flame and is, therefore, the concentration of the element in a sample.

EVAPORATIVE COOLING

Involves the adiabatic exchange of heat between air and water spray or wetted surface. The water assumes the wetbulb temperature of the air, which remains constant during its traverse of the exchanger.

WHITECAPS

Foam or spray on wave tops caused by stronger winds (usually above force 4).

JET CONDENSER

A direct contact heat exchanger in which steam to be condensed comes into direct contact with the cooling water (cold condensate) which is usually introduced in the form of a spray from a jet.

DODGER

A shield against rain or spray on a ship's bridge.

LIPPER

1. Slight ruffling or roughness on a water surface. 2. Light spray from small waves

BARBER

A strong wind carrying damp snow or sleet and spray that freezes upon contact with objects, especially the beard and hair.

SPRAY NOZZLE

A nozzle from which a liquid fuel is discharged in the form of a spray.

BOILER PRIMING

An induction of boiler water caused by the steam flow into the steam line. The water may be in the form of a spray or a solid body.

AIR-ATOMIZING OIL BURNER

A burner for firing oil in which the oil is atomized by compressed air which is forced into and through one or more streams of oil, breaking the oil into a fine spray.
