Dynamic Viscosity of Gases Calculator

Formula

The formula to calculate the Dynamic Viscosity (μ) is:

$\mu = \frac{a \cdot T^{1/2}}{1 + \frac{b}{T}}$

Definition

Dynamic Viscosity Fluid is the measure of fluid's resistance to flow when an external shear force is applied between the layers of fluid. Sutherland Experimental Constant 'a' refers to a constant value experimentally obtained by Sutherland correlation. It is a crucial parameter for determining dynamic viscosity of gases. Absolute temperature of fluid refers to the measurement of intensity of heat energy present in fluid in kelvin scale. Where 0 K, represents as the absolute zero temperature. Sutherland Experimental Constant 'b' refers to a constant value experimentally determined by Sutherland correlation. It is a crucial parameter for determining dynamic viscosity of gases.

Example Calculation

Let's assume the following values:

Sutherland Experimental Constant 'a' = 0.008
Absolute Temperature of Fluid (T) = 293 Kelvin
Sutherland Experimental Constant 'b' = 211.053

Using the formula:

$\mu = \frac{0.008 \cdot 293^{1/2}}{1 + \frac{211.053}{293}} \approx 0.0796003933111279$

The Dynamic Viscosity is approximately 0.0796003933111279 Pascal Second.
