Sentences with phrase «emittance from»

All Radiant Emittance detectors, radiometers or spectrometers, are encased in a metal box removing from the signal Radiant Emittance from the opposite direction to the «View Angle».

The most common characteristics are: swelling of the injected joint (s), heat emittance from the area and mild to moderate lameness.

Not exact matches

If he happens to chip a tile while removing a gap filler, he could retrieve an emittance wash tool from the airlock to repair the tile.

Net radiant energy flux from the plane of the detector in the absence of the detector and box would the vector sum of Irradiances (= Emittance for a collimated beam).

Well from a computational accuracy point of view, the measure of intensity is accurate to better than 1 % so long as you are more than 10 emitting surface diameters away from a non-point source; but the point is there is NO per unit area section in an Intensity specification; but there is in Radiance, or Spectral Radiance, which these graphs properly are, and also in «emittance» which is simply W / m ^ 2 without regard for directional properties, or wavelength or frequency properties, which would intorduce the spectral terms at least.

The next module of the MIT course, from the World's pre-eminent Technical University, claims Emittance (W / m ^ 2) is Emissivity (dimensionless).

- Low - e windows (the «e» stands for emittance or emissivity) feature a metallic oxide coating that doesn't let heat or UV - rays pass through, which will keep warm air in during the winter and prevent heat from the blazing summer sun from turning your home into a sauna in the summer.

A low cloud cover increases the sky emittance and hence «back» radiation.The surface energy balance then shows that the surface temperature increases and the convection heat loss from the ocean decreases: thus the nighttime subsurface ocean temperature does not decrease as much compared to that for a clear sky.

There is something very fishy in the spectral graphs bandied about from calculations regarding the emittance and reflectance of N2 and O2.
