5. Carbon dioxide and oxygen filled in two large chambers in whch the species concentrations are maintained at fixed values and connected by a circular tube whose length and diameter are 1m and 50 mm respectively. The system is maintained at a total pressure of 10 atm and 25° C. The partial pressure of CO2 at one end is 190 mm Hg. While at the other end is 95 mm Hg. (1) Estimate the rate of mass transfer. (ii) Find the partial pressure of CO2 at 0.75 m from the end where the partial pressure is 190 mm Hg. Diffusivity of CO2-O2 at 150 C is 1.995 x 105 m2/s. (10) (Apr/May '08) 5.
