Suspension property of static fluids (completion and workover fluids)

Input(s)

dd: Particle Diameter (μm)(\mu \mathrm{m})

ρp\rho_{p}: Density of Solid Particle (g/cm3)\left(\mathrm{g} / \mathrm{cm}^{3}\right)

ρf\rho_{f}: Density of Fluid (g/cm3)\left(\mathrm{g} / \mathrm{cm}^{3}\right)

g: Acceleration Owing to Gravity (ft/s2)\left(\mathrm{ft} / \mathrm{s}^{2}\right)

μ\mu : Fluid Viscosity (cP)(\mathrm{cP})

Output(s)

v: Particle Settling Velocity (in/s)

Formula(s)

v=d2(ρpρf)g(μ)(4.5106)v=\frac{d^{2}\left(\rho_{p}-\rho_{f}\right) g}{(\mu)\left(4.5 \cdot 10^{6}\right)}
