Hi, does anybody know the value of the mass diffusivity of the air and of the CO. Thanks, Gabriel

Dear Gabriel

Mass diffusivity is defined as 'mass diffusivity of A in the B'. So, I guess that your question is 'mass diffusivity of CO in the air'. Following reference might be helpful for you but datum for CO is absent. I guess that mass diffusivity of CO in the air is order of 1.e-05 m2/sec.

Sincerely, Jinwook
