Two streams flow into a 500.0-gallon tank. The first stream is 10.0 wt % ethanol and 90.0 wt\% hexane (mixture density is p10.680 After the tank has been filled, which takes 17.0 minutes, an analysis of its contents determines that it is 60.0 wt % ethanol and 40.0 . wt\%hexane. Estimate the density of the final mixture and the mass and volumetric flow rates of the two feed streams. Mass flow rate of stream 1: kg/min Volumetric flow rate of stream 1: L/min Mass flow rate of stream 2: kg/min Volumetric flow rate of stream 2 : Wimin. Density of mixure: g/cm3 Two streams flow into a 500.0-gallon tank.
