Oxygen and nitrogen diffuse in a counter-current ideal gas manner through 0.0054m diameter circular channel of length 0.0097m at a temperature of 298K and a total pressure of 100000pa. The partial pressure of oxygen decreases from 50pa to 0pa .The diffusion is aided by a bulk velocity of 0.01m/s.what is the fluxof oxygen in micro mol per second per square meter to an accuracy of at least two decimal places.
