Input(s)
\(\mathrm{K}\): Consistency Index \((\mathrm{cP})\)
\(\mathrm{n}\): Power-Law Index (fraction)
\(\gamma\): Shear Rate \((1 / \mathrm{s})\)
Output(s)
\(\tau\): Shear Stress \(\left(\mathrm{lbf} / 100 \mathrm{ft}^{2}\right)\)
Formula(s)
\[
\tau=\mathrm{K} *\left(\gamma^{\mathrm{n}}\right)
\]
