Question

Mass transfer by diffusion and convection

Answer 1

Mass Transfer Due to the Bulk Motion of a Fluid. Convection is mass transfer due to the bulk motion of a fluid. For example, the flow of liquid water transports molecules or ions that are dissolved in the water.

Answer 2

Explanation:

Mass Convection

Convective mass transfer is really diffusion (the random movement of molecules) in combination with advection (molecules being carried along with the motion of the fluid). To better understand mass transfer via convection, it is important to consider boundary layers in fluids flowing over surfaces.
