Dear all, It is stated in a literature that: Solubility = [87 cm^3(STP) H20]/ [cm^3 polymer*atm] = 93,28 (g H20/cm^3 polymer)/ (g H20/cm^3 air) where the storage conditions is 28 degress celsius and 70% relative humidity, at 1 atm. My question, how do i convert from the first unit to...

Dear all, I'm trying to solve the diffusion PDE for my system, shown below: \frac{\partial C}{\partial t} = D (\frac{\partial^2 C}{\partial r^2} + \frac{1}{r} \frac{\partial C}{\partial r}) where C is the concentration, changing with time t and radius r. D is the diffusion...
