Home > Mass transfer
Mass transfer is the phrase commonly used in engineering for physical processes which involve molecular and convective transport of atoms and molecules within physical systems. Mass transfer includes both mixing and separation processes.- Some common examples of mass transfer processes are the evaporation of water from a pond to the atmosphere; the diffusion of chemical impurities in lakes, rivers, and oceans from natural or artificial point sources; mass transfer is also responsible for the separation of components in an apparatus such as a distillation column.

In astronomy, mass transfer is the process by

starFor alternate meanings see star (disambiguation Hubble Space Telescope of the Sagittarius Star Cloud in the Milky Way Galaxy. A star is any massive gaseous celestial body in outer space. Stars appear as shining points in the nighttime sky that twinkle bec, fills its Roche lobeThe Roche lobe is the region of space around a star in a binary system within which orbiting material is gravitationally bound to that star. If the star expands past its Roche lobe, then the material outside of the lobe will fall into the other star. and becomes gravitationally bound to a second body, usually a compact object ( white dwarfA white dwarf is a star with a color like most other stars, but with low absolute brightness. Such stars were discovered in the 19th century; the first ones found were white. The color of a star is a measure of the surface temperature: white stars are lik, neutron starThis article is about the celestial body. Neutron Star was a 1966 Hugo award winning short story by Larry Niven A neutron star is a compact star in which the weight of the star is carried by the pressure of free neutrons. It is a so called degenerate star or black holeThis article is about the astronomical body. For other uses, see Black hole (disambiguation). roche limit. Infalling matter forms an accretion disk, with some of the matter being ejected in highly energetic polar jets. A black hole is a concentration of m), and is eventually accreted onto it. It is a common phenomenon in binary systems, and may play an important role in some types of supernovae, and pulsars.
