Two streams flow into 500 gallon tank. The first stream contains 10 wt% ethanol and 90 wt% hexane ( density =0.68 g/cc) while the second stream contains 90 wt% ethanol and 10 wt% hexane ( (density= 0.780 g/cc). The tank gets filled in 22 min. After the tank gets filled in the sample analysis suggests 60 wt% ethanol and 40 wt% hexane.
1. Carry out degree of freedom analysis.
2. Perform the calculations of mixed stream density and flow rate of each stream.
