Question:
A thin plastic membrane is used to separate helium from a gas stream. Under steady-state conditions the concentration of helium in the membrane is known to be 0.02 and 0.005k mol/m3 at the inner and outer surfaces, respectively. If the membrane is 1 mm thick and the binary diffusion coefficient of helium with respect to the plastic is 10-9 m2/s, what is the diffusive flux?

I have been teaching since I started my graduation 3 years ago. As a student, working as Teacher/PA has been tough but made me learn the needs for student and how to help them resolve their problems efficiently. I feel good to be able to help out students because I'm passionate about teaching. My motto for teaching is to convey the knowledge I have to students in a way that makes them understand it without breaking a sweat.
