Comparison between Heat and Mass Transfer Results

4 COMPARISON BETWEEN HEAT AND MASS TRANSFER RESULTS 

Quite frequently heat transfer problems have their analogs in mass transfer. This can be fortuitous if recognized, as time and labor can be saved when solving a given problem. One approach that can be very helpful in exposing the similarities between two problems requires the use of dimensionless

In two previously worked-out applications, Example 7.1 and Example 7.6, both situations were reduced to the identical dimensionless differential equations 

This result may now be interpreted in terms of a heat transfer application (Example 7.1) or a mass transfer application (Example 7.6).
