Einstein equation effective viscosity
Input(s)
\(\emptyset\): Porosity (volume fraction of the spheres)
\(\mu_{0}\): Viscosity of Suspending Medium (g/cm s)
Output(s)
\(\mu_{\text {eff: }} \quad\) Effective Viscosity (g/cm s)
Formula(s)
\[
\mu_{\mathrm{eff}}=\mu_{0} *\left(1+\frac{5}{2} * \varnothing\right)
\]
