Liquid hazardous wastes are blended in a cstr to maintain a minimum energy content before burning them in a hazardous waste incinerator. the energy content of the waste currently being fed is 8.0 mj/kg (mega-joules/kilogram). a new waste is injected in the flow line into the cstr. it has an energy content of 10.0 mj/kg. if the flow rate into and out of the 0.20 m3cstr is 4.0 l/s, how long will it take the effluent from the cstr to reach an energy content of 9 mj/kg?
