Examine how a $4-$stage countercurrent extraction system works. An aqueous solution containing $20\%$ solute is introduced into the first stage at a rate of $1000$ kg$/$h $*$ r$.$ You know that the solute concentration leaving stage $2$ is $6\mathrm{.}2\%.$ Using Equation, determine overall recovery of the distribution coefficient, fresh solvent mass rate of the raffinate, and extract solute concentration in the final extract and raffinate Verify your in $)$ using McCabe Thiele Method. The solvent $(1800$ ky$/$hr c solute$)$ enters at the last stage. You know that the water and the solvent used.
