If cells are grown in a 10ml bioreactor which flows fresh me

If cells are grown in a 10ml bioreactor which flows fresh media (containing 0.01g/mL glucose) into the system and continually ejects an equal volume of the existing media, what flow rate must be used to maintain a 0.005g/mL glucose level in the system? Assume a well-mixed system. Please show your work

Solution

if the media glucose concentration is 0.005g/ml then also the media flow rate will me 10ml. because same amount of media is ejects at the same time.
