Following distillation, vodka (an ethanol and water solution) that is 96 mass% ethanol is fed into a mixer and diluted with a stream that is 4 mass% ethanol. The stream that exits is split into two parts, part one that is bottled up and sold as non-flavored vodka, and the other part that is further processed and flavored.

The following conditions are known about this step of the process:

1. The production rate of nn-flavored vodka is 560kg/h

2. 80% of the vodka exiting the mixer is sold as non-flavored vodka

3. The flowrate of the 96% ethanol stream accounts for of the total amount fed into the mixer.

   a) Perform a degree of freedom analysis for each system boundary and specify an order in which the problem could be solved to determine all the unknowns.

   b) Calculate the amount of vodka that is diverted for additional processing (kg/h).

   c) calculate the flowrate of the streams entering the mixer (kg/h) and the final concentration of non-flavored vodka. Include a check of your answer
