A Stirred Tank with Volume, V, Has a Feed Stream

question 57

Multiple Choice

A stirred tank with volume, V, has a feed stream of concentrated floor cleaner flowing into it at a rate of f . The flow stream has a concentration of c_i. The outlet stream also flows at f but with a concentration of c, the concentration of the floor cleaner solution in the tank. The rate of change of the concentration is proportional to the difference between c_i and c with proportionality constant of f/V: . If the tank volume is 1000 L, the flow rate is 10 L/min, the inlet concentration is 1.0, and the initial concentration of the floor cleaner in the tank is 0.0, how long until the concentration in the tank is 0.7?
