Rate equations for heat and mass transfer can also be written. Here, however, complications arise because of the fact that heat is transferred from the bulk of the liquid phase to the liquid-gas interface entirely as a result of the temperature potential, but from the interface to the bulk of the gas phase, heat is transferred as the result by two mechanisms. On the gas-phase side of the interface, heat is transferred as the result of a temperature potential, and the latent heat
associated with the mass transfer is transferred by these two mechanisms are separated as the two terms on the right side of the equation (8).
With these ideas, equations for the heat- transfer processes indicated in equations (6) and (8) can be written separately. For the liquid phase transfer
The enthalpy-balance equations are the rate equations given above can be combined to give a design equation. These equations will relate the change in gas-phase temperature and molal humidity to the rates of heat and of mass transfer to, or from, the gas-phase. Thus, combining equation (8) with equations (10) and (11).
