A distillation column is fed with two feed streams (stream F1 and F2) and produces a top product (stream F3) and a bottom product (stream F4).

Stream F1 enters the column at a rate of 2530 kg h-1

containing 40% w/w component A, 30% w/w component B and 30% w/w component C and stream F2 contains 40% w/w component A and 60% w/w component B.

Stream F3 contains only components A and B, the flow rate of component B in the stream is 1770 kg h-1

and 80% of component A entering the column leaves in this stream. Stream F4 eaves the column at a rate of 2448 kg h-1

Evaluate the flow rates of stream F2 and F3.
