Question

Two streams flow into a 500 US gallon tank. The first stream is 10.0 wt% ethanol and 90.0 wt% hexane and has a density of rho
1
= 0.68 g/cm
3
. The second stream is 90.0 wt% ethanol and 10.0 wt% hexane and has a density of rho
2
= 0.78 g/cm
3
. After the tank is filled, which takes 22 min, the mixture is 60.0 wt% ethanol and 40.0 wt% hexane.
a) Draw and label the diagram for this system.
b) Estimate the density of the mixed stream. Use this density to calculate the final mass of the mixture in the filled tank.
c) Calculate the mass (in kg/min) and volumetric (in L/min) flow rates of the two streams, assuming that they fill the tank at a constant rate.
