Many heat transfer problems are accompanied by mass transfer. For example, water cooling in cooling towers used in thermal power plants involves both heat transfer and mass transfer. A typical example of mass transfer is the immediate spread of a room freshener in an air-conditioned room. Convective mass transfer closely resembles convective heat transfer. The analogy between mass transfer
