- Company Profile:
A light petroleum distillate that is used in space heaters, cook stoves, and water heaters and is suitable for use as a light source when burned in wick-fed lamps. Kerosene has a maximum distillation temperature of 400 degrees Fahrenheit at the 10-percent recovery point, a final boiling point of 572 degrees Fahrenheit, and a minimum flash point of 100 degrees Fahrenheit. Included are No. 1-K and No. 2-K, the two grades recognized by ASTM Specification D 3699 as well as all other grades of kerosene called range or stove oil, which have properties similar to those of No. 1 fuel oil. Also see Kerosene-type jet fuel.
Industry:Energy
A term generally used to describe artificial light. The term is often used when referring to a "bulb" or "tube."
Industry:Energy
The distance on the earth's surface measured, respectively, north or south of the equator and eastor west of the standard meridian, expressed in angular degrees, minutes,and seconds.
Industry:Energy
A family, an individual, or a group of up to nine unrelated persons occupying the same housing unit. "Occupy" means that the housing unit is the person's usual or permanent place ofresidence.
Industry:Energy
A humidifier adds moisture to the air(often needed in winter when indoor air is very dry). It may be a portable unit or attached to the heating system.
Industry:Energy
The moisture content of air. Relative humidity is the ratio of the amount of water vapor actually present inthe air to the greatest amount possible at the same temperature.
Industry:Energy
Undiscovered coal resources in beds that may reasonably be expected to exist in known mining districts under known geologic conditions. In general, hypothetical resources are in broad areas of coal fields where points of observation are absent and evidence is from distant outcrops, drillholes, or wells. Exploration that confirms their existence and better defines their quantity and quality would permit their reclassification as identified resources. Quantitative estimates are based on a broad knowledge of the geologic character of coalbed or region. Measurements of coal thickness are more than 6 miles apart. The assumption of continuity of coalbed is supported only by geologic evidence.
Industry:Energy
A term generally used to describe a man-made source of light. The term is often used when referring to a "bulb" or "tube".
Industry:Energy
The opposition to power flow in an AC circuit. Also, any device that introduces such opposition in the form of resistance, reactance, or both. The impedance of a circuit or device is measured as the ratio of voltage to current, where a sinusoidal voltage and current of the same frequency are used for the measurement; it is measured in ohms.
Industry:Energy
A solar absorber surface that has high absorbtance at wavelengths corresponding to that of the solar spectrum and low emittance in the infrared range.
