Question- A permeation membrane separates an inlet air stream (79 mol% N2, 21 mol% O2) into a permeate stream and a reject stream. The inlet stream conditions are 293K, 0.5 MPa and 2 mol/min; the conditions for both outlet streams are 293 K and 0.1 MPa. If the permeate stream is 50 mol% O2, and the reject stream is 13 mol% O2, what are the volumetric flow rates(L/min) of the two outlet streams?
