Consider cross flow of gas X over an object having a characteristic length of L = 0.1 m. For a Reynolds number of I 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 thermo physical properties, what is the average convection mass transfer coefficient?
