Two streams and $S_2)$ of similar liquid mixtures enter the center of a distillation

column. The action of the column separates the combined mixture into several

components of different volatilities $($and different densities$),$ which leave the column at

the top $(S_3),$ middle $(S_4),$ and bottom $(S_5).$ Given the following data,

The mass flow rate of stream $2=$

$k\frac{g}{s}(2s.f)$

The mass flow rate of stream $3=$

$k\frac{g}{s}(2s.f)$

The mass flow rate of stream $4=$

$k\frac{g}{s}(2s.f)$

The density of stream $4=$

$k\frac{g}{m^3}(2$ s$.$f$)$

Note: in order to get all the correct answers $($in particular for the density$),$ you must

not round off the numbers during the calculation until you get to the final answers.
