Humid air is travelling through a drying channel, removing water from it. Inside the channels, several sorts of solid particles of various shapes are inserted to remove water vapour from the air via diffusion. Because the concentration of water vapour in this case is quite low, believing that the apparent physical attributes of water vapour and air are identical is a legitimate assumption. Inside the channel, the operating pressure 101.3 kPa while the temperature was 82 oC. (a) If a single 31 mm diameter sphere is placed into the channel, what will be the mass transfer coefficient in (kg mol/s m2. Pa)? (b) What is the mass transfer coefficient if a packed bed with a void fraction of 0.51 is made up of numerous spheres with the same diameter as in (a)?
