| absolute viscosity | Force per unit area applied tangentially to a fluid, causing unit rate of displacement of parallel planes separated by a unit distance; units in CGS system: poise. (05 Mar 2000) |
|---|---|
| anomalous viscosity | The viscous behaviour of nonhomogenous fluids or suspensions, e.g., blood, in which the apparent viscosity increases as flow or shear rate decreases toward zero. (05 Mar 2000) |
| apparent viscosity | <physiology> This refers to the ratio of shear stress to shear rate in a fluid, this ratio is dependent on the rate of shear. (09 Oct 1997) |
| blood viscosity | The internal resistance of the blood to shear forces. The in vitro measure of whole blood viscosity is of limited clinical utility because it bears little relationship to the actual viscosity within the circulation, but an increase in the viscosity of circulating blood can contribute to morbidity in patients suffering from disorders such as sickle cell anaemia and polycythemia. (12 Dec 1998) |
| magnetic viscosity | <physics> A magnetic field in a conducting fluid will damp fluid motions perpendicular to the field lines, similar to ordinary viscosity, even in the absence of sizeable mechanical forces or electric fields. (09 Oct 1997) |
| relative viscosity | The ratio of the viscosity of a solution or dispersion to the viscosity of the solvent or continuous phase. (05 Mar 2000) |
| viscosity | <chemistry> A physical property of fluids that determines the internal resistance to shear forces. (18 Nov 1997) |
| coefficient of viscosity | The value of the force per unit area required to maintain a unit relative velocity between two parallel planes a unit distance apart. (05 Mar 2000) |
| Poiseuille's viscosity coefficient | An expression of the viscosity as determined by the capillary tube method; the coefficient η = (πPr4t/8vl), where P is the pressure difference between the inlet and outlet of the tube, r the radius of the tube, l its length, and v the volume of liquid delivered in the time t. If volume is in cm3, time is in seconds, and l and r are in cm, then n will be in poise. (05 Mar 2000) |
| newtonian viscosity | The viscosity characteristics of a newtonian fluid. (05 Mar 2000) |
| dynamic viscosity | The internal or molecular frictional resistance of a fluid by Newton's law of viscosity as the ratio of the applied force per unit area to the relative velocity of adjacent fluid layers (produced by the force). (05 Mar 2000) |
| kinematic viscosity | A measure used in studies of fluid flow; the dynamic viscosity, u, in poises divided by the density of the material; units: stokes. (05 Mar 2000) |
| atomic number | <chemistry> Symbol Z. The number of protons in the nucleus of an atom and also its characteristic atomic number. The atomic numbers of the known elements form a complete series from 1 (hydrogen) to 103 (lawrencium). (16 Dec 1997) |
| Avogadro's number | <physics> The number of molecules in a mole (gram molecular weight) of a substance, equals 6.02 x 1023 molecules. (09 Oct 1997) |
| Brinell hardness number | A number related to the size of the permanent impression made by a ball indenter of specified size (usually 10 mm in diameter) pressed into the surface of the material under a specified load: where P = applied load in kg, D = diameter of the ball in mm, and d = diameter of the impression in mm.
