The formula to calculate the Terminal Velocity (Vterminal) is:
\[ Vterminal = \frac{2}{9} \cdot r^2 \cdot (\rho_1 - \rho_2) \cdot g / \mu_{viscosity} \]
Terminal Velocity is the maximum velocity attainable by an object as it falls through a fluid (air is the most common example). Radius is a radial line from the focus to any point of a curve. Density of the first phase in a two-phase microstructure. Density of the second phase in a two-phase microstructure. Acceleration due to Gravity is acceleration gained by an object because of gravitational force. The Dynamic Viscosity of a fluid is the measure of its resistance to flow when an external force is applied.
Let's assume the following values:
Using the formula:
\[ Vterminal = \frac{2}{9} \cdot 0.2^2 \cdot (8500 - 6000) \cdot 9.8 / 1.02 \approx 213.507625272331 \]
The Terminal Velocity is approximately 213.507625272331 Meter per Second.
