A water solution of $1,500$ kg$/$h containing $2$ wt$\%$ nicotine in water is stripped with a kerosene stream of$3,000$ kg$/$h in a countercurrent stage tower. The exit water is to contain only $5\%$ of the original nicotine. Determine the number of theoretical stages using $($a$)$ McCabe$-$Thiele graphical solution; $($b$)$ KSB analytical method.wt fraction nicotine in water solution wt fraction nicotine in ker

$3,000k\frac{g}{h}$ in a countercurrent stage tower. The exit water is to contain only $5\%$ of the original nicotine. Determine the number of theoretical stages using $($a$)$ McCabe$-$Thiele graphical solution; $($b$)$ KSB analytical method.
