Why is the mass flow rate of a chemical species into the domain not equal to the product of the mass fraction and the bulk mass flow rate?

The net mass flow rate of a species at an inlet boundary includes contributions from both convection and diffusion. The convection component is determined from your input of species concentration while the diffusion component is calculated by FLUENT.
