Yоu hаve designed а cylindricаl biоreactоr to culture stem cells for tissue grafts. The porous graft permits vitamins to flow into the interior. A 50 g/min buffer solution containing 4 mg/mL of Vitamin B flows into the graft. What is the expected total mass flow rate (g/s) and mass flow rate (g/s) of Vitamin B out of the system? What is the total mass flow (g) of Vitamin B in a 6 hour period? Lab results show the Vitamin B mass flow rate is 125 mg/min. Make conjectures about what has happened in this experiment.
