Two large tanks are connected by a truncated conical duct as shown in Figure. The diameter at z=0 is 6mm and the diameter at z=0.2m is 10mm. Gas compositions in the tanks are given in terms of mole percentages. The pressure and temperature throughout the system are 1atm and 25C, respectively, and DAB=3105m2/s. a) Determine the initial molar flow rate of species A between the vessels. b) What would be the initial molar flow rate of species A if the conical duct were replaced with a circular tube of 8mm diameter?
