the rate at which a material vaporizes from the liquid or solid state when compared to a known material's vaporization rate. The known reference material is usually normal butyl acetate(N-BuAc).
A measure of the quantity of a liquid converted to vapour in a unit of time. Among single component liquids, the rate varies directly with the surface area, the temperature and the vapour pressure, and inversely with the latent heat of vaporisation of the liquid.
The ratio of the time required to evaporate a measured volume of a liquid chemical to the time required to evaporate the same volume of a reference liquid (usually ethyl ether). In general, the higher the ratio, the lower the boiling point.
The rate at which a material vaporizes from a liquid or solid state compared to the vaporization rate of a known standard (normal butyl acetate=1).
The rate at which a liquid is changed to a vapor under standard conditions, usually compared to the rate of another substance that evaporates very quickly.
the rate at which the solvent in a paint and medium mixture evaporates into the air. Solvents like turpentine evaporate fast, solvents like Gamsol are much slower which greatly decreases your exposure to solvent vapors. Oil colors and the binder in the mediums do not start to dry until all the solvent has evaporated.
The speed with which any liquid evaporates.
The time required for a given amount of a material (usually n butyl Acetate or ethyl Ether Standard must be quoted).
The rate at which water is absorbed into the air passing through the cooling media. For practical purposes, this rate is measured in gallons of water per hour (or minute).
The evaporation rate of a material is given in reference to a standard chemical, usually butyl acetate, which evaporates fairly quickly. Butyl acetate has an evaporation rate of one. Toxic or flammable chemicals with an evaporation rate close to or greater than one may pose health or fire hazards.
The volume of liquid water evaporated per unit area in unit time, usually measured as the depth of liquid water lost per unit time from the whole area.
The rate are which a particular material will vaporize (evaporate) when compared to the rate of vaporization of a known material. The evaporation rate can be useful in evaluating the health and fire hazards of a material. The known material may be ethyl ether with a vaporization rate designated at 1.0. Vaporization rates of other solvents or materials are then classified as: 1. Fast evaporating if greater than 3.0. 2. Medium evaporating if 0.8 to 3.0. 3. Slow evaporating, if less than 0.8
The rate at which a material is converted to a vapor (evaporates) at a given temperature and pressure compared to the evaporation rate of water. Health and fire hazard evaluations of materials involve consideration of the evaporation rate as one aspect of the evaluation.
The rate at which a particular substance will vapourize (evaporate) when compared to the rate of a known substance such as ethyl ether. This term is especially useful for health and fire-hazard considerations.
In hydrologic terms, the quantity of water, expressed in terms of depth of liquid water, which is evaporated from a given surface per unit of time. It is usually expressed in inches depth, per day, month, or year.
The ratio of the rate of vaporization of a given material relative to the rate of vaporization of n-butyl acetate (n-BuAc), which is assigned a value of one (1.0). Vaporization rates of other solvents or materials are then classified as: FAST evaporating if greater than 3.0 Examples: Methyl Ethyl Ketone (MEK) = 3.8, Acetone = 5.6, Hexane = 8.3 MEDIUM evaporating if 0.8 to 3.0 Examples: 95% Ethyl Alcohol = 1.4, VM&P Naphtha = 1.4, methyl isobutyl ketone = 1.6 SLOW evaporating if less than 0.8 Examples: Xylene = 0.6, n-butyl alcohol = 0.4, Water - 0.3, Mineral Spirits = 0.1
The rate of evaporation for a liquid, in unitless values relative to butyl acetate, which is assigned an evaporation rate of 1.
The rate at which a material will vaporize (evaporate) when compared to the known rate of vaporization of a standard material. The evaporation rate can be useful in evaluating the health and fire hazards of a material. The designated standard material is usually normal butyl acetate (NBUAC or n-BuAc), with a vaporization rate designated as 1.0. Vaporization rates of other solvents or materials are then classified as
The rate at which a liquid changes to vapor at normal room temperature.
