16. CVEN 3401: A completely mixed continuous bioreactor used for growing penicillin operates as a zero order system. The input, glucose, is converted to various organic yeasts. The flow rate

to this system is 20 L/min, and the conversion rate constant is 4 mg/(min-L). The influent glucose concentration is 800 mg/L, and the effluent must be less than 100 mg/L. What is the smallest reactor capable of producing this conversion?
