radiant flux उदाहरण वाक्य

उदाहरण वाक्य

1. During operation, at high temperature and radiant flux, metal ions tend to penetrate the silica, depleting the inside of the tube.
2. Other tests, such as the " critical radiant flux " test ( ASTM E648 / NFPA 253 ) are more suitable for establishing ignitability.
3. Light with wavelengths outside the visible spectrum reduces luminous efficacy, because it contributes to the radiant flux while the luminous flux of such light is zero.
4. Typical variables to be optimized at the target include the total radiant flux, the angular distribution of optical radiation, and the spatial distribution of optical radiation.
5. The irradiance of a give area of the earth's surface changes as the angle of incidence of the radiant flux from the sun changes throughout the year.
6. In 1879, Jo ~
   ef Stefan observed that the total radiant flux from a blackbody is proportional to the fourth power of its temperature and stated the Stefan Boltzmann law.
7. The half-value layer ( HVL ) is the thickness of a layer of material required to reduce the radiant flux of the transmitted radiation to half its incident magnitude.
8. If the source emitted uniformly in all directions, the total radiant flux would be about 18.40 mW, since there are 4 & pi; steradians in a sphere.
9. In practice, it is important note how radiant flux varies with direction, the size of the solid angle subtended by the source at each point on the surface, and the orientation of the surface.
10. This led to the Federal Consumer Products Safety Commission passing 16 CFR Part 1209, which sets safety standards covering four product attributes for cellulose insulation only : settled density, corrosiveness, critical radiant flux and smoldering combustion.
