The article investigates heat exchange and resistance when non-Newtonian, chemically reacting liquids, whose viscosity depends on the flow rate, the temperature, the pressure, and the degree of conversion, flow through flat pipes.doi:10.1007/BF00827362V. A. Gerasimenko...
Does intrinsic viscosity depend on solvent? The increase of viscosity depends on thetemperature, the type of polymer and solvent, the concentration of the polymer, and the molar mass of the polymer. Is density intrinsic or extrinsic? Density is an intrinsic property, while weight is an extrinsic...
- Viscosity depends strongly on temperature. In liquids it usually decreases with increasing temperature, whereas, in most gases, viscosity increases with...- Look up viscosity in Wiktionary, the free dictionary. Viscosity (commonly perceived as "thickness", or resistance to pouring) is the measure...
Viscosity is a fundamental property of the mantle which determines the global geodynamical processes. According to the microscopic theory of defects and laboratory experiments, viscosity exponentially depends on temperature and pressure, with activation energy and activation volume being the parameters. The...
The viscosity of air depends mostly on the temperature. At 15 °C, the viscosity of air is 1.81 × 10-5 kg/(m·s) , 18.1 μPa·s or 1.81 × 10-5 Pa·s . 空气的粘度主要取决于温度。在15℃时,空气的粘度为1.81 × 10-5 kg/(m·s) ,18.1 μPa·s或1.81 × 10-5 Pa·s。 The...
Absolute viscosity, also called dynamic viscosity, measures a substance's resistance to flow. It is determined experimentally by sandwiching a liquid or gas between two plates and applying a known amount of pressure to move the top plate — the dynamic viscosity depends on the pressure, the ...
Section 3: Dependency of Viscosity on Temperature The Viscosity of liquids decreases with increasing temperature. For gas it`s the opposite; viscosity increase with increasing temperature. Back Next Another commonly equation: Where n depends on the type of gas (1 < n < 0,75) ...
Some exploratory laboratory experiments are described, using a working fluid (glycerine) whose viscosity depends strongly on temperature. Surface cooling produces a thin, viscous sheet which is driven away from regions of upward convection, and then plunges down steeply into the less viscous interior,...
The moment of inertia of a body depends upon View Solution Among solids, liquids and gases, which one can have all the moduli of elasticity? View Solution Discuss the effect of temperature on the viscosity of liquids and gases. View Solution Explain the effect of increasing the temperature ...
Elongational viscosity, which comes into plan in the drawing of extrudates, is analogously defined. In polymers, the viscosity depends not only on temperature and, less strongly, on pressure, but also on the level of shear stress (or shear rate). SeeViscosity,Power Law, andPseudoplastic Fluid...
