At 6:59 units of tube's length (10 metres) are supposed to be in metres and not cubic metres

Can u estimate the diffussive flux when there is also a bulk flow inside the tube ?

okay so does diffusion flow rate have two equations?
@aqeelraja4750

it doesnt. one is for the concentration gradient which is then plugged into ficks first law equation.

Can Ficks law be applied to hair? there are layers to hair but im not sure if there is any diffusion.

I guess you could compare in vitro results to calculations and see!

@@JustinG1057 yeah we have a TEWL meter for skin at work that uses this law and used it on hair but were not sure what the results meant. I guess I could try and do some calculations. Math is not my strong suit tho lol

hello, I think you did not balance the units correctly, when you say J=kg/s it really should be kg/m^2*s instead. The concentration delta over the length becomes kg/m^2 not kg alone. This leads to the mass of oxygen flowing through the tube to be incorrect also, because its actually 2.895e-6 kg/m^2*s, and the cross sectional area needs to be considered.

Really interesting! I would like to ask you how can I calculate the final concentration in gas phase if I don’t know the Flux J and the final. I am trying to calculate the concentration of VOC compound in gas phase in function of concentration in water

It is a good explanation but it is oversimplified. The diffusion process is not linear because the concentration at L=0 and L=L changes with time. So the flux (rate of diffusion) gets smaller and smaller.. So in order to get a concentration profile along the diffusional distance over time then you should use the 2nd Fick's law.

If you know so much then why are you watching this video, This isn't meant to be a complicated explanation. I just started learning this topic and it was perfect for me

It's oversimplified because it's algebra and not calculus, bud. Remember that the goal of this is to that confused people can grasp the concepts that they are learning in class, not to research about the flow rate of oxygen in real life.
