Sep 12, 2022 · The difference is fluid friction, both within the fluid itself and between the fluid and its surroundings. We call this property of fluids viscosity. Juice has low viscosity, whereas syrup has high viscosity. The precise definition of viscosity is based on laminar, or nonturbulent, flow.
May 7, 2021 · The dynamic viscosity coefficient divided by the density is called the kinematic viscosity and given the Greek symbol nu. nu = mu / r Re = V * L / nu The units of nu are length^2/sec. Here's a Java program to calculate the coefficient of viscosity and the Reynolds number for different altitude, length, and speed.
Mar 2, 2024 · The formula of Viscosity, η = \(\frac{2ga^2(Δρ)}{9v}\) The other units of Viscosity are N s m-2 or Pascal seconds (Ps) The coefficient of viscosity is a force when the velocity of the gradient is unity and the area of contact is unit area. Viscosity has a dimensional formula of [ML-1 T-1]. Check More:
For some mixtures of two liquids it was observed that at a low shear stress, the viscosity is dominated by a liquid with high viscosity and at high shear stress to be dominated by a liquid with the low viscosity liquid. The higher viscosity is more dominate at low shear stress. Reiner and Phillippoff suggested the following formula:
The viscosity is calculated with Equation \(\ref{1}\) \[ \eta =K t \label{1}\] where \(K\) is the value of a liquid with known viscosity and density such as water. Once the value of K is known, the viscosity can be determined by measuring the amount of time the test liquid flows between the two graduated marks. Units of Measure:
2 days ago · The centimetre-gram-second or CGS unit of coefficient of viscosity, η is . dyne-sec/ cm 2 which is equal to Poise. Where one poise is exactly 0.1 Pa·s. The meter-kilogram-second or MKS unit is: Kilogram per meter per second or. Kg m-1 s-1. Coefficient of Viscosity Unit and Dimension. Since, the formula for coefficient of viscosity is given by,
How does viscosity of gases vary with temperature ? The viscosity of gases is, in general, increasing with temperature. The additional movement of the gas molecules is actually causing more contact, thus interaction in between molecules leading to an increase in viscosity.
