Definitions
- Describing the ability of a material to allow light or radiation to pass through it. - Referring to the percentage of light or radiation that is transmitted through a material. - Talking about the measurement of the amount of light or radiation that passes through a material.
- Describing the ability of a material to allow liquids or gases to pass through it. - Referring to the degree to which a material can be penetrated by a liquid or gas. - Talking about the measurement of the rate at which a liquid or gas can pass through a material.
List of Similarities
- 1Both words describe the ability of a material to allow something to pass through it.
- 2Both words are used in scientific contexts.
- 3Both words are measured using quantitative methods.
- 4Both words are important in understanding the properties of materials.
- 5Both words can be affected by factors such as temperature and pressure.
What is the difference?
- 1Type of substance: Transmittance refers to the ability of a material to allow light or radiation to pass through it, while permeability refers to the ability of a material to allow liquids or gases to pass through it.
- 2Measurement: Transmittance is measured as a percentage of the amount of light or radiation that passes through a material, while permeability is measured as a rate of flow of a liquid or gas through a material.
- 3Units: Transmittance is measured in percentage or decimal values, while permeability is measured in units such as cm/s or mDarcy.
- 4Application: Transmittance is often used in optics and spectroscopy, while permeability is often used in geology, engineering, and materials science.
- 5Factors affecting it: Transmittance can be affected by factors such as the thickness and composition of the material, while permeability can be affected by factors such as the size of the pores in the material and the viscosity of the liquid or gas.
Remember this!
Transmittance and permeability are both terms used to describe the ability of a material to allow something to pass through it. However, transmittance refers specifically to the ability of a material to allow light or radiation to pass through it, while permeability refers to the ability of a material to allow liquids or gases to pass through it. Additionally, the two terms are measured differently and are used in different scientific contexts.
