Two liquid streams are flowing at constant rates into ablender. One is benzene, which flows at a measured rateof 20.0 L/min, and the other is toluene. The blendedmixture enters a storage tank (inner diameter = 5.5 m)equipped with a sight gauge. During an interval in whichno liquid leaves the storage tank, the liquid level in thetank is observed to increase by 0.15 meters over a one-hour period. Calculate the flow rate of toluene into theblender (L/min) and the composition of the tankcontents (wt% benzene).
