A countercurrent leaching system is recovering oil from soybeans with five stages. On a volumetric basis, liquid flow rate/solids flow rate \(=1.36\). Recovery of oil in the solvent is \(97.5 \%\). The solvent is pure. Determine the effective equilibrium constant, \(m_{E}\), where \(m_{E}\) is \(\left(\mathrm{kg} / \mathrm{m}^{3}\right.\) of solute in solvent \() /\left(\mathrm{kg} / \mathrm{m}^{3}\right.\) of solute in solid) and is given by equation \(\mathrm{y}=\mathrm{m}_{\mathrm{E}} \mathrm{X}\). Assume the overall volumetric flow rates are constant.
