The formula to calculate the Sphericity of a Particle given its volume, surface area, and equivalent diameter is:
\[ \Phi_p = \frac{6 \cdot V_s}{S_{\text{particle}} \cdot D_e} \]
Sphericity of a Particle is a measure of how closely the shape of an object resembles that of a perfect sphere. The Volume of One Spherical Particle is the capacity of a single particle or the volume occupied by one particle. The Surface Area of a Particle is a measure of the total area that the surface of the object occupies. The Equivalent Diameter is the diameter equivalent to the given value.
Let's assume the following values:
Using the formula:
\[ \Phi_p = \frac{6 \cdot 17.6}{10.4 \cdot 0.55} \approx 18.4615384615385 \]
The Sphericity of the Particle is approximately 18.4615384615385.
