The mean radiant temperature is the average effect of radiation from surrounding surfaces. At the center of the room this temperature can be taken as being equal to the mean surface temperature

Radiant is the energy of light.
Examples: thrmometers, pyrometres, thermocouples.
A pyrometer or pyrometric cones are used to measure furnace and kiln temperatures resulting from radiant heat. A pyrometer is a ceramic base into which 4 to 6 pyrometric cones…, which melt at different temperatures, are inserted. Placing this into a furnace opening which is out of the normal gas passes, in direct view of the flame, and can be sealed from in-leakage of cooler air, will give you a general idea of a flame temperature (radiant heat). If it is inserted into a gas pass it will give convective heat temperatures. By knowing the temperature at which each cone melts you can get a close approximation of a flame or furnace temperature. More modern line of sight infrared-laser thermal imaging guns can give direct readings of surface or flame temperatures, and are more accurate. Thermocouples though must be used in convective gas passes.
Theoretically false. An object at the temp of absolute zero would emit no energy or radiation. However, absolute zero does not exist in nature (as far as we know), therefor, i…n a practical sense the statement is true.
The wavelength of radiation is related to the frequency of radiation. Frequency is the rate of vibration of a wave source. High frequency vibrations produce short waves and lo…w frequency vibrations cause longer waves. A low temp. source emits primarily low-frequency, long-wavelength waves. A high temp. does just the opposite.
In Irish the name Laoise (lee-sha) means "radiant girl"...probably where we get the name Louise in English.
All object at any temperature irradiate radiation, yet, net total energy may be in minus.In example, earth do reflect and irradiate energy to the sun but in total we recieved …energy from the sun at approx 1400 W/m2
illuminated, glowing, reflecting.
Radiant energy is the energy of electromagnetic waves. The quantity of radiant energy may be calculated by integrating radiant flux (or power) with respect to time and, like a…ll forms of energy, its SI unit is the joule. The term is used particularly when radiation is emitted by a source into the surrounding environment. Radiant energy may be visible or invisible to the human eye.
It means a smile that seems to shine.
The answer to this is given by Wien's displacement law, at least for an ideal "black body" as the radiating source. The law states that the distribution of wavelengths has es…sentially the same shape at all temperatures (with the scale varying), with the peak wavelength λpeak occuring at: λpeak = b/T, where b is Wien's displacement constant and T is the absolute temperature. In S.I. units, b = 2.898×10−3 m·K to four significant figures (the unit is metre-Kelvin, not millikelvin).
'Radiant' as adjective: in Hindi it's 'Deeptimaan'.
MRT = A1t1 + A2t2 + A3t3 devided by A1 +A2 + A3 A= Area of element t = Temperature °C
It varies greatly from product to product and from market to market. The best way to get an answer is to put an ad on Craigslist telling what you want installed, the more deta…il you can give the better the quote will be... ie.. "3/4 inch, unfinished oak hardwood over wood subfloor, new construction, 400 sq feet, need it done this week, paying cash.". The lesson here is that the more detail you put in the ad, the better the quote.. You will have to understand that not every installer has Golden Hands, some are thieves & butchers, so you may not always want the low bidder..
