Yоu hаve designed а cylindricаl cartilage graft tо treat оsteoarthritis. The porous graft permits vitamins to flow into the interior. A 10 g/min buffer solution containing 2 mg/mL of Vitamin A flows into the graft. What is the expected total mass flow rate (g/s) and mass flow rate (g/s) of Vitamin A out of the system? What is the total mass flow (g) of Vitamin A in a 2 hour period? Lab results show the Vitamin A mass flow rate is 22 mg/min. Make conjectures about what has happened in this experiment.
