Two air stripping units are being installed at industrial sites. One will be used to strip Toluene from a ground water source that is pumped at a flow rate of 100 L/min. The other will be pumped at the same flow rate but will be used to strip Trichloroethylene. Both have been designed with a stripping factor of 6. What is the ratio of the two air flow rates (Qtoluene/QTCE)?
