An aqueous solution of sodium chloride containing 0.2 wt% NaCl and 99.8% water is fed at a rate of 2.0 kg/s into a distillation unit. Pure water vapor exits the top of the unit via stream 2 at a rate of 1.6 kg/s while the remaining sodium chloride solution (now with a mass fraction x kg NaCl/kg) exits the bottom of the unit via stream 3 at a steady rate of m3 kg/s. In labeling the flowchart shown above, which of the following should stream 1 be labeled with? Select all that apply. 0.998 kg H₂O/kg Ox (kg NaCl/kg) 1.6 kg H₂0/s 2.0 kg/s Om3 (kg/s) (1-x) kg NaCl/kg 0.002 kg NaCl/kg

Question
Help with the following question.
An aqueous solution of sodium chloride containing 0.2 wt% NaCl and 99.8% water is fed at a rate of 2.0 kg/s into a distillation unit.
Pure water vapor exits the top of the unit via stream 2 at a rate of 1.6 kg/s while the remaining sodium chloride solution (now with a
mass fraction x kg NaCl/kg) exits the bottom of the unit via stream 3 at a steady rate of m3 kg/s.
In labeling the flowchart shown above, which of the following should stream 1 be labeled with? Select all that apply.
0.998 kg H₂O/kg
Ox (kg NaCl/kg)
1.6 kg H₂0/s
2.0 kg/s
Om3 (kg/s)
(1-x) kg NaCl/kg
0.002 kg NaCl/kg
