mean free path of molecules
1Mean free path — In physics, the mean free path is the average distance covered by a moving particle (such as an atom, a molecule, a photon) between successive impacts (collisions) [1] which modify its direction or energy or other particle properties. Contents 1… …
2mean free path — noun : the average distance traversed between collisions by particles (as molecules of a gas or free electrons in metal) in a system of agitated particles called also free path * * * Physics, Chem. (in a collection of moving particles)the average …
3mean free path — noun Date: 1879 the average distance traversed between collisions by particles (as molecules of a gas or free electrons in metal) in a system of agitated particles …
4mean free path — noun the average distance travelled between two similar events; especially by molecules in a gas or liquid, electrons or phonons in a crystal or neutrons in a moderator …
5Mean free time — Molecules in a fluid constantly collide off each other. The mean free time of a molecule in a fluid is the average time between collisions. The mean free path of the molecule is the product of the average speed and the mean free time. These… …
6Free molecular flow — describes the fluid dynamics of gas where the mean free path of the molecules is larger than the size of the chamber or of the object under test. For tubes/objects of the size of several cm, these means pressures well below 10 3 torr. This is… …
7Vacuum distillation — At atmospheric pressure, dimethyl sulfoxide boils at 189°C. Under a vacuum, it distills off into the connected receiver at only 70°C. Vacuum distillation is a method of distillation whereby the pressure above the liquid mixture to be distilled is …
8Distillation — Distiller and Distillery redirect here. For other uses, see Distiller (disambiguation) and Distillery (disambiguation). For other uses, see Distillation (disambiguation). Laboratory display of distillation: 1: A heating device 2: Still pot 3:… …
9Lattice Boltzmann methods — (LBM) is a class of computational fluid dynamics (CFD) methods for fluid simulation. Instead of solving the Navier–Stokes equations, the discrete Boltzmann equation is solved to simulate the flow of a Newtonian fluid with collision models such as …
10Orders of magnitude (pressure) — This is a tabulated listing of the orders of magnitude in relation to pressure expressed in pascals. Magnitude Pressure lbf/in2 or dB Item 10−13 Pa 0.1 pPa Interstellar space pressure (approximate) 10 …
