62de Laval nozzle — Diagram of a de Laval nozzle, showing approximate flow velocity (v), together with the effect on temperature (t) and pressure (p) A de Laval nozzle (or convergent divergent nozzle, CD nozzle or con di nozzle) is a tube that is pinched in the… …
63De Laval nozzle — A de Laval nozzle (or convergent divergent nozzle, CD nozzle or con di nozzle) is a tube that is pinched in the middle, making an hourglass shape. It is used as a means of accelerating the flow of a gas passing through it to a supersonic speed.… …
64hemorheology — The science of the flow of blood in relation to the pressures, flow, volumes, and resistances in blood vessel s, especially in terms of blood viscosity and red cell deformation in the microcirculation. [hemo …
65Polyethylene — or polythene (IUPAC name poly(ethene)) is a thermoplastic commodity heavily used in consumer products (notably the plastic shopping bag). Over 60 million tons of the material are produced worldwide every year. Description Polyethylene is a… …
66Marsh funnel — The Marsh funnel viscometer is a simple device for measuring viscosity from the time it takes a known volume of liquid to flow from the base of a cone through a short tube. It is particularly used by mud engineers to check the quality of drilling …
67D'Alembert's paradox — In fluid dynamics, d Alembert s paradox (or the hydrodynamic paradox) is a contradiction reached in 1752 by French mathematician Jean le Rond d Alembert.[1] D Alembert proved that – for incompressible and inviscid potential flow – the drag force… …
68Netflow — architecture NetFlow is a network protocol developed by Cisco Systems for collecting IP traffic information. NetFlow has become an industry standard for traffic monitoring and is supported by platforms other than Cisco IOS and NXOS such as… …
69Rheology — is the study of the flow of matter: mainly liquids but also soft solids or solids under conditions in which they flow rather than deform elasticallyW. R. Schowalter (1978) Mechanics of Non Newtonian Fluids Pergamon ISBN 0 08021778 8] . It applies …
70Hypersonic — In aerodynamics, hypersonic speeds are speeds that are highly supersonic. Since the 1970s, the term has generally been assumed to refer to speeds of Mach 5 (5 times the speed of sound) and above. The hypersonic regime is a subset of the… …
