A pure substance A having density of 800 kg/m^3 (56 lbm/ft^3) is diffusing into a binary mixture of A and B. If the velocity of A is 4 cm/hr (1.2 in/hr) into the mixture and the velocity of B is 3.6 cm/hr out of the mixture, what is the total bulk velocity? Assume that the density of pure B is 900 kg/m^3 (63 lbm/ft^3) and that the mixture density is 890 kg/m^3 (61 lbm/ft^3).
