What is the equasion for flow
Flow = (pressure diff x pi x r4)/(length x viscosity x 8)
What is the equasion for Diffusion
Diffusion = (solubility x area x pressure diff)/(thickness x sqrt GMW)
What is Fick's Law
Diffusion is proportional to the partial pressure difference and the area of the membrane and inversely proportional to the thickness of the membrane
