The formula to calculate the Dynamic Viscosity of Fluid (μd) is:
\[ \mu_d = \frac{\tau \cdot y}{u} \]
Dynamic Viscosity of Fluid is the measure of its resistance to flow when an external force is applied. Shear stress on the lower surface refers to the amount of shear force that acts on a small element of the surface of the lower plate parallel to the adjacent fluid layer. Distance Between Plates Carrying Fluid is the vertical distance between the parallel plates in a parallel plate viscometer experimental setup. Velocity of Moving Plate is the rate of change of position of the lower plate with respect to time, relative to the fixed upper plate. This induces a shear stress on the fluid.
Let's assume the following values:
Using the formula:
\[ \mu_d = \frac{58.506 \cdot 0.02}{14.7} \approx 0.0796 \]
The Dynamic Viscosity of Fluid is approximately 0.0796 Pascal Second.
