Cutting slip velocity
Input(s)
PV: Plastic Viscosity (cP)
MW: Mud Weight (ppg)
Dp: Diameter of Particle (in.)
DenP: Density of Particle (ppg)
Output(s)
\(\mathrm{V}_{\mathrm{s}}\): Slip Velocity \((\mathrm{ft} / \mathrm{min})\)
Formula(s)
\[
\mathrm{V}_{\mathrm{s}}=0.45 *\left(\frac{\mathrm{PV}}{\mathrm{MW} * \mathrm{Dp}}\right) *\left(\left(\left(\frac{36800}{\left(\frac{\mathrm{PV}}{\mathrm{MW} * \mathrm{Dp}}\right)^{2}}\right) * \mathrm{Dp} *\left(\frac{\mathrm{DenP}}{\mathrm{MW}}-1\right)\right)+1^{-1}\right)^{0.5}
\]
