0.5: 1.75 kg/s of a solid containing 0.55 kg soluble material (Liquid), is to be washed with 2.8 kg/s
pure solvent in a counter-current unit. The final residue is to contain not more than 0.1% solute when
dried. Find the number of stages given that the amount of solution in under flow varies with solute
concentration according to the relation: W-0.2x+ 0.3.
