The formula to calculate the Dynamic Viscosity (μ) is:
\[ \mu = \frac{a \cdot T^{1/2}}{1 + \frac{b}{T}} \]
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.
Let's assume the following values:
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.
