An oil and water stream is to be separated using a settling tank. The feed to the tank $($stream $1)$ is $43\mathrm{.}5$ wt $\%$ oil and enters the tank at a total flowrate of $1832$ kg$/$hr$.$ The oil layer rises to the top and exits as stream $2$ and the water layer settles at the bottom and exits as stream $3.$ The separation is not perfect, in that the top layer is $100\%$ oil, the bottom product water layer still contains $8\%$ of the entering oil. You are to find the individual mass flowrates of the product streams, and their ratio $($oil layer$/$water layer$),$ and the composition of the water layer in wt $\%.$ What is the $\%$ recovery of the oil?
