Meaning of emissivity

Webster

emissivity (n.)

Tendency to emission; comparative facility of emission, or rate at which emission takes place, as of heat from the surface of a heated body.

Tendency to emission; comparative facility of emission, or rate at which emission takes place;

the rate of emission of heat from a bounding surface per degree of temperature difference between the surface and surrounding substances (called by Fourier external conductivity).

emissivity Sentence Examples

  1. Emissivity is a material property that describes how efficiently it emits thermal radiation.
  2. The emissivity of a material is dependent on its temperature, wavelength, and surface roughness.
  3. A material with high emissivity emits thermal radiation more efficiently than a material with low emissivity.
  4. The emissivity of a material can be measured using an emissivity meter.
  5. Common materials have emissivity values that range from 0 to 1, with 0 being perfectly reflective and 1 being perfectly black.
  6. The emissivity of a material can be increased by roughening the surface or by applying a coating.
  7. The emissivity of a material is important in a variety of applications, such as heat transfer, thermal imaging, and remote sensing.
  8. For example, materials with high emissivity are used in solar energy collectors to absorb sunlight, while materials with low emissivity are used in spacecraft to minimize heat loss.
  9. The emissivity of a material can also be used to determine its temperature.
  10. By measuring the emissivity and the intensity of the thermal radiation emitted by a material, it is possible to calculate its temperature.
