"Webb24 feb. 2024 · Calculate the Liquid's Viscosity. The final equation you'll need to calculate the liquid's viscosity is this: Viscosity = (2 x (ball density – liquid density) x g x a^2) ÷ (9 x v). g is a constant, which is 9.8 m/s^2 (acceleration due to gravity) and v is the velocity of the ball falling through the liquid, and a is the radius of the ball ...

WebbFor hydrocarbons, viscosity is far higher and conductivity far lower. The high viscosity will lead to the accumulation of heated emulsion around the coil that isolates the mass from further heat transfer because the ΔT is reduced. In theory, we therefore expect a large reduction of heat transfer with the coil in question when used in hydrocarbons. Webb2. Change by viscosity temperature. The viscosity of liquid usually changes according to temperature. Especially in case of lubricants (hydrocarbons), viscosity significantly differs depending on temperature variation. [Viscosity Index] Viscosity Index (VI) represents the relation between the viscosity of oils and temperature.
