Suspension property of static fluids (completion and workover fluids)
Input(s)
\(d\): Particle Diameter \((\mu \mathrm{m})\)
\(\rho_{p}\): Density of Solid Particle \(\left(\mathrm{g} / \mathrm{cm}^{3}\right)\)
\(\rho_{f}\): Density of Fluid \(\left(\mathrm{g} / \mathrm{cm}^{3}\right)\)
g: Acceleration Owing to Gravity \(\left(\mathrm{ft} / \mathrm{s}^{2}\right)\)
\(\mu\) : Fluid Viscosity \((\mathrm{cP})\)
Output(s)
v: Particle Settling Velocity (in/s)
Formula(s)
\[
v=\frac{d^{2}\left(\rho_{p}-\rho_{f}\right) g}{(\mu)\left(4.5 \cdot 10^{6}\right)}
\]
