b$)$ A chemical reactor system is fed $100$kmo$\frac{l}{h}$ of reactant $A,$ which is then mixed with a recycle stream. In the reactor, $60\%$ of A that enters the reactor is converted to product $B.$ the mixture exiting the reactor goes to the separation unit where all of the product B plus $20\%$ of A is removed, and the rest of $A$ is recycled and mixed with the fresh feed.

i$)$ Draw a flow sheet and define all the process streams

ii$)$ How many kmo$\frac{l}{h}$ of reactant A enters into the reactor

$[5]$

iii$)$ Calculate the overall conversion and single pass conversion
