The measure of potential energy of a fluid.

Related Terms

AGGLOMERATION

The potential of the system for particle attraction and adhesion.

DIELECTRIC STRENGTH

A measure of the ability of an insulating material to withstand electric stress (voltage) without failure. Fluids with high dielectric strength (usually expressed in volts or kilovolts) are good electrical insulators. (ASTM Designation D 877.)

COPPER STRIP CORROSION

A qualitative measure of the tendency of a petroleum product to corrode pure copper.

SALINITY

A measure of the concentration of dissolved mineral substances in water.

ENVIRONMENTAL CONTAMINANT

All material and energy present in and around an operating system, such as dust, air moisture, chemicals, and thermal energy.

ASH

A measure of the amount of inorganic material in lubricating oil. Determined by burning the oil and weighing the residue. Results expressed as percent by weight.

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.

ASPIRATING PSYCHROMETER

A device which draws sample of air through it to measure humidity.

INTERFACIAL TENSION (IFT)

The energy per unit area present at the boundary of two immiscible liquids. It is usually expressed in dynes/cm (ASTM Designation D 971.)

GROUND ABSORPTION

The dissipation of energy in radio waves because of absorption by the ground over which the waves are transmitted.
