tömegátadási

Tömegátadási, a Hungarian term, translates directly to "mass transfer" in English. It is a fundamental concept in physics and engineering, referring to the net movement of a substance, such as a chemical species, through a system. This movement can occur due to various driving forces, including concentration gradients, pressure differences, or temperature variations.

Mass transfer is a crucial process in a wide range of natural phenomena and industrial applications. In nature, it plays a role in processes like evaporation of water from lakes, diffusion of oxygen into blood, and the distribution of pollutants in the atmosphere. Industrially, mass transfer principles are applied in separation processes like distillation, absorption, and extraction, where components of a mixture are separated based on their differing affinities for various phases.

The rate of mass transfer is influenced by several factors, including the properties of the substances involved, the geometry of the system, and the presence of any interfaces between different phases. Understanding and quantifying mass transfer is essential for designing and optimizing many chemical and physical processes, ensuring efficient operation and product quality. This field of study is often referred to as mass transfer engineering.
