Q. One handbook gives the following correlation for mass transfer into a flow fluid from a single solid sphere DPkRTd=0.276{(μdvρ)1/2(Dρμ)1/3} In one set of experiments in air for a napthalene sphere 1.26 cm in diameter, the function of the Reynolds and Schmidt numbers in braces equals 980 . The diffusion coefficient of napthalene in air is 0.074 cm2/sec at 25∘C. What is the film thickness for mass transfer? What is the surfacerenewal time? R=82.057 cm3⋅atm/mol.K b) Both the penetration theory and the surface-renewal theory presume diffusion into a semiinfinite slab. What is the difference between them?
