1Incandescent light bulb — The incandescent light bulb, incandescent lamp or incandescent light globe is a source of electric light that works by incandescence, (a general term for heat driven light emissions which includes the simple case of black body radiation). An… …
2Wet-bulb temperature — The wet bulb temperature is a type of temperature measurement that reflects the physical properties of a system with a mixture of a gas and a vapor, usually air and water vapor. Wet bulb temperature can have several technical meanings:… …
3Dry-bulb temperature — The dry bulb temperature is the temperature of air measured by a thermometer freely exposed to the air but shielded from radiation and moisture. Dry bulb temperature is the temperature that is usually thought of as air temperature, and it is the… …
4Hot bulb engine — The hotbulb, or hot bulb engine or vaporizing oil engine is a type of internal combustion engine. It is a surface ignition engine in which the superheated fuel is ignited by being brought into contact with oxygen rich fresh air, rather than by a… …
5Maximum parcel level — The maximum parcel level (MPL) is the highest level in the atmosphere that a moist convectively rising air parcel will reach after ascending through the free convective layer (FCL) and reaching the equilibrium level (EL), near the tropopause. As… …
6Convective condensation level — The convective condensation level (CCL) represents the height where an air parcel becomes saturated when lifted adiabatically to achieve buoyant ascent. It marks where cloud base begins when air is heated from below to the convective temperature …
7Bus bulb — A bus bulb, also called a bus boarder or bus border, is an arrangement by which a sidewalk is extended outwards for a bus stop; typically the bus bulb replaces roadway that would otherwise be part of a parking lane. With bus bulbs or boarders, a… …
8Wet Bulb Globe Temperature — The Wet Bulb Globe Temperature (WBGT) is a composite temperature used to estimate the effect of temperature, humidity, and solar radiation on humans. It is used by industrial hygienists, athletes, and the military to determine appropriate… …
9DRYTRA level — A level of temperatures at which exhaust trails must occur even if the ambient air is completely dry. This flight level is determined with the help of a chart called a tephigram. A tephigram is an aerological map on which temperatures and… …
10Contact level — Contact Con tact (k[o^]n t[a^]kt), n. [L. contactus, fr. contingere, tactum, to touch on all sides. See {Contingent}.] 1. A close union or junction of bodies; a touching or meeting. [1913 Webster] 2. (Geom.) The property of two curves, or… …
