Viscosity, английский
- Viscosité
- Measurement of a fluid`s resistance to flow. the common metric unit of absolute viscosity is the poise, which is defined as the force in dynes required to move a surface one square centimeter in area past a parallel surface at a speed of one centimeter per second, with the surfaces separated by a fluid film one centimeter thick. in addition to kinematic viscosity, there are other methods for determining viscosity, including saybolt universal viscosity (suv), saybolt furol viscosity, engier viscosity, and redwood viscosity. since viscosity varies in inversely with temperature, its value is meaningless until the temperature at which it is determined is reported.
- Вязкость
- A measure of resistance to flow in a liquid (molasses in january has high viscosity while molasses in august has lower viscosity).
- The ratio of the shear stress existing between laminae of moving fluid and the rate of shear between these laminae.
- The internal frictional resistance exhibited by a fluid in resisting a force which tends to cause the liquid to flow.
- The state of a liquid which moves slowly
- The resistance of a liquid to flow.
- Вязкость. мера внутреннего сопротивления материала потоку. вязкость снижается с повышением температуры (мос, 4). в метеорологии и исследованиях по загрязнению атмосферного воздуха она определяется как коэффициент ц в выражении x = r{du/dh), где т — напряжение сдвига, выражаемое через силу на единицу площади (в единицах си — паскаль, па), п — средняя скорость ветра и h — высота. эту величину следует называть «вязкостью», но не «динамической вазкостью». кинематическая вязкость — вязкость, деленная на плотность жидкости. турбулентная вязкость в метеорологии — вязкость, обусловленная взаимодействием вихревых движений в турбулентном потоке. эти вихревые движения влияют на обмен количества движения между соседними слоями, аналогичный (но в значительно более широких масштабах) обмену молекулами при молекулярной вязкости (вмо).
- The internal flow resistance of a fluid. (also see intrinsic viscosity and relative viscosity.)
- The resistance of a fluid to flow, which can be estimated by using a marsh funnel.
- S measure of a fluid`s resistance to flow. in the si system, the viscosity units are ns/m2, pa s or kg/(m s)
- The measure of a liquid’s ability to flow under varying temperature conditions. in automobiles, viscosity most often refers to the “weight” of a motor oil, which is designated using number and letter grades established by the society of automotive engineers. oils with low numbers such as 5w or 10w flow easily at low temperatures (the “w” stands for winter). oils with high numbers such as 30 or 40
- Measure of a fluid’s resistance to flow. this is typically measured as the time required for a standard quantity of fluid at a certain temperature to flow through a standard orifice. the higher the value, the more viscous the fluid. viscosity varies inversely with temperature, so the measurements are always expressed together. tests are typically conducted at 40°c and 100°c.
- Measure of the resistance to flow, or internal friction, of a fluid. viscosity changes with temperature so the temperature at which the measure has made must always be specified. see also apparent viscosity, kinematic viscosity.
- The property of a fluid, semi-fluid or semi-solid substance that causes it to resist flow. its numerical value is based on the ratio of shear stress to the rate of shear during flow. the standard unit of absolute viscosity in the english system is the reyn, expressed as lb-s/in.2. the standard unit of viscosity in the cgs and iso system is the poise, expressed as dyne-s/cm2. conversion from one
- A measurement of a liquids resistance to change of shape or flow. also referred to as flow resistance.
- Quality, state or degree of being viscous. that property of a body by virtue of which, when flow occurs inside it, forces arise in such a direction as to opposite the flow.
- The resistance of a fluid to deformation by shear or tensile stress. lower viscosity equates to greater fluidity.
- Measure of the resistance of liquid to deform under shear stress.
- Kinematic viscosity.
- Used to describe a fluid’s resistance to flow. for example, a highly viscous fluid won’t flow as easily as one with a low viscosity.
