1a) (10 pts) Evaluate the diffusion coefficient of carbon dioxide in air at 20C and atmospheric pressure by selecting appropriate diffusivity parameter equation. 1b) (10 pts) Experimental value for CO2 in air at 273K at 1 atm is obtained as 0.136 cmBy using below given equation calculate the corresponding diffusivity parameter at 273K and compare against the experimental value (% difference). (120,51 120,12) Use: MWair= 29 and MWc02= 44, and Appendix B for o (in units) and /K (in K units) values. 1.5 6) DABT2 = 1 D ABT1 1a) (10 pts) Evaluate the diffusion coefficient of carbon dioxide in air at 20C and atmospheric pressure by selecting appropriate diffusivity parameter equation. 1b) (10 pts) Experimental value for CO2 in air at 273K at 1 atm is obtained as 0.136 cmBy using below given equation calculate the corresponding diffusivity parameter at 273K and compare against the experimental value (% difference).
