Mass Transfer Coefficient

The mass transfer coefficient describes how easily a substance moves from one location to another, such as from a solid surface into a liquid or gas. Think of it as a rate factor that indicates how quickly a molecule like oxygen or nutrients spreads or transfers through a medium. Higher coefficients mean faster transfer, which is important in processes like water purification, chemical reactions, or biological systems. Essentially, it measures the efficiency of substance exchange between different phases, helping engineers and scientists optimize systems for better performance and safety.
