See R-Value.

Category:Energy Terms

A measure of the capacity of a material to resist heat transfer. The R-Value is the reciprocal of the conductivity of a material (U-Value). The larger the R-Value of a material, the greater its insulating properties.

Category:Energy Terms

A method of winds aloft observation essentially the same as a pilot balloon observation except the height data is derived from the radiosonde observation rather than from assumed ascension rates.

Category:Meteorology

The operation of temporarily holding two lines together by seizing.

Radio Direction and Range

Category:Abbreviations

An arch to mount the radar, usually at the stern of the boat.

Category:Sea Words

An object designed to increase the radio reflectivity of a boat so that it is more visible on radar. Many small boats are made with fiberglass and other materials that do not reflect radar very well on their own.

Category:Sea Words

A radar which is used to obtain the azimuth elevation, and slant range of an airborne target.

Category:Meteorology

Apparatus in which radar techniques are used to determine the range, elevation, and azimuth of a balloonborne target, to computer upper-air wind data. It is a type of rawin system.

Category:Meteorology

A system in which radar techniques are used to determine the range, elevation, and azimuth of a radar target carried a!oft by a radiosonde, so that wind data may be obtained along with the other meteorological data.

Category:Meteorology

A compressor belonging to the group of dynamic compressors. Characterized by radial flow. (Centrifugal)

Category:Sea Words

In radiometry, a measure of the intrinsic radiant intensity emitted by a radiator in a given direction.

Category:Meteorology

A thin, reflective foil sheet that exhibits low radiant energy transmission and under certain conditions can block radiant heat transfer; installed in attics to reduce heat flow through a roof assembly into the living space.

Category:Energy Terms

Ceiling panels that contain electric resistance heating elements embedded within them to provide radiant heat to a room.

Category:Energy Terms

Energy that transmits away from its source in all directions.

Category:Energy Terms

The energy of any type of electromagnetic radiation. Also called radiation.

Category:Meteorology

A type of radiant heating system where the building floor contains channels or tubes through which hot fluids such as air or water are circulated. The whole floor is evenly heated. Thus, the room heats from the bottom up. Radiant floor heating eliminates ...
