cross flow of gas

6.57   Consider cross flow of gas X over an object having a characteristic length of L = 0.1 m. For a Reynolds num- ber of 1 X 104, the average heat transfer coefficient is 25 W/m2 · K. The same object is then impregnated with liquid Y and subjected to the same flow conditions. Given the following thermophysical properties, what is the average convection mass transfer coefficient?

 

v (m2/s)            k (W/m · K)            a (m2/s)

 

Gas X              21 X 10-6                      0.030                 29 X 10-6

Liquid Y       3.75 X 10-7                      0.665              1.65 X 10-7

Vapor Y        4.25 X 10-5                      0.023              4.55 X 10-5

Mixture of gas X–vapor Y:            Sc = 0.72
