5gas — gasless, adj. /gas/, n., pl. gases, v., gassed, gassing. n. 1. Physics. a substance possessing perfect molecular mobility and the property of indefinite expansion, as opposed to a solid or liquid. 2. any such fluid or mixture of fluids. 3. any… …
6Gas-filled tube — See also: Gas discharge lamp A gas filled tube, also known as a discharge tube, is an arrangement of electrodes in a gas within an insulating, temperature resistant envelope. Although the envelope is typically glass, power tubes often use… …
7Pressure drop — For other uses, see Pressure Drop (disambiguation). Pressure drop is a term used to describe the decrease in pressure from one point in a pipe or tube to another point downstream. Pressure drop is the result of frictional forces on the fluid as… …
8Gas exchange — or respiration takes place at a respiratory surface a boundary between the external environment and the interior of the body. For unicellular organisms the respiratory surface is Fick s law we can predict that respiratory surfaces must have: *a… …
9Gas chromatography-mass spectrometry — (GC MS) is a method that combines the features of gas liquid chromatography and mass spectrometry to identify different substances within a test sample. Applications of GC MS include drug detection, fire investigation, environmental analysis,… …
10Pressure-Correction Methods — refer to a class of methods used in computational fluid dynamics for solving the Navier Stokes equations normally for incompressible flows. Common Properties The equations solved in this approach arise from the implicit time integration of the… …
