Meaning of emissivity
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
- Emissivity is a material property that describes how efficiently it emits thermal radiation.
- The emissivity of a material is dependent on its temperature, wavelength, and surface roughness.
- A material with high emissivity emits thermal radiation more efficiently than a material with low emissivity.
- The emissivity of a material can be measured using an emissivity meter.
- Common materials have emissivity values that range from 0 to 1, with 0 being perfectly reflective and 1 being perfectly black.
- The emissivity of a material can be increased by roughening the surface or by applying a coating.
- The emissivity of a material is important in a variety of applications, such as heat transfer, thermal imaging, and remote sensing.
- 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.
- The emissivity of a material can also be used to determine its temperature.
- By measuring the emissivity and the intensity of the thermal radiation emitted by a material, it is possible to calculate its temperature.
