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)

Vs\mathrm{V}_{\mathrm{s}}: Slip Velocity (ft/min)(\mathrm{ft} / \mathrm{min})

Formula(s)

Vs=0.45(PVMWDp)(((36800(PVMWDp)2)Dp(DenPMW1))+11)0.5\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}
