A new 850 cm^2 membrane is being tested for use in a hemodialysis device. During testing, a model fluid mixture is used that contains solutes with average radii of 1 nm. In one test, the concentration of the filtrate is found to be 2.17 g/L, while the concentration on the feed-side surface is 8.52 g/L.
Prior experimentation showed that the mass transfer coefficient in the device was approximately 9 × 10-4 cm/s.
A) If the total filtration flow rate is measured to be 0.56 cm^3/s, what is the solute concentration in the feed solution?
B) Explain how you could determine the average membrane pore radius for this membrane using this information.
