A system contains two components, A and B and three unit operations. A series of processes take place to obtain a final product in stream 5 by separating some of component B in stream 3. A portion of components A and B are also recycled (stream 6) back to the feed stream (stream 1). The mass flowrate of the feed stream is 76 kg/h.

In this figure, x_i represents mass fraction of component i and _i is used for the mass flow rates of streams (when i is an integer) or components (when i is not an integer).

Find the mass flow rate of streams 3 (₃) in kg/h
