massansiirtoa
Massansiirto, or mass transfer, is the net movement of mass within or between physical systems caused by gradients in concentration, temperature, or pressure. It describes how components migrate from regions of higher chemical potential to regions of lower potential and is fundamental to many natural and engineered processes. In Finnish usage, the term massansiirtoa often appears in technical contexts describing these transport phenomena.
Mass transfer occurs mainly through diffusion, convection, and phase-change mechanisms. Diffusion arises from random molecular motion
Mathematically, mass transfer is treated with species mass balances. Diffusive flux is often expressed as J =
Applications span chemical engineering unit operations, environmental remediation, food processing, and pharmaceutical manufacturing. Understanding mass transfer
