emissivity वाक्य

उदाहरण वाक्य

1. In this case, Kirchhoff's law of equality of radiative absorptivity and emissivity holds.
2. Heat loss is further reduced by the low-emissivity of the glass that is used.
3. The applied current was particularly effective in reducing surface oxides that increased the emissivity of the filaments.
4. Absorptivity, reflectivity, and emissivity of all bodies are dependent on the wavelength of the radiation.
5. Windows  incorporating low emissivity glass, together with insulated spacer bars and extra deep window frames.
6. A black body has an emissivity of 1 and a perfect reflector has an emissivity of 0.
7. A black body has an emissivity of 1 and a perfect reflector has an emissivity of 0.
8. During the night, the atmosphere cools somewhat, but not greatly, because its emissivity is low.
9. For that reason, incorrect selection of emissivity will give inaccurate results when using infrared cameras and pyrometers.
10. This solution assumes that the emissivity is the same at both wavelengths and cancels out in the division.
