In the separation process illustrated below, fresh feed stream F consists of 20% A and 80% B on a mass basis. F mixes with recycle stream R to produce mixed stream M, which enters the separator. The mass ratio of A:B in stream M is 2:3. Product stream P, which leaves the separator at 100 kg/h, is pure A, while waste stream W is 5 mass % A. Recycle stream R is 80 mass % A. (a) Find all unknown stream flow rates. (b) Calculate the recycle ratio.
