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 exists 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 non-flavored vodka is 560 kg/hr

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) Calculate the amount of vodka that is diverted for additional processing (kg/hr)? (Answer: 140kg/hr)

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

   (answer: m1= 467 m2= 233 x3= 0.654)
