Mud rheology calculations - Bingham plastic model
Input(s)
\(\tau_{\mathrm{y}}\): Yield Stress \(\left(\mathrm{lb} / 100 \mathrm{ft}^{2}\right)\)
\(\mu_{\mathrm{p}}\): Bingham Plastic Viscosity \((\mathrm{cP})\)
\(\gamma\): Shear Rate \((1 / \mathrm{s})\)
Output(s)
\(\tau\): Shear Stress \(\left(\mathrm{lb} / 100 \mathrm{ft}^{2}\right)\)
Formula(s)
\[
\tau=\tau_{\mathrm{y}}+\left(\mu_{\mathrm{p}} * \gamma\right)
\]
