3) A very large tank of unknown volume, equipped with a double blade agitator is initially filled with 5.5 liters of an aqueous sodium sulfate (Na,SO,) solution having a concentration of 109 g NazSO4/L. The specific gravity (S.G.) of the solution is 1.091. Into the tank, a solution having a concentration of 625 g NazSO4/L flows at a rate of 0.032 L/min. The S.G. of the inlet stream is 1.250. At the single outlet to the tank, the flowrate is 0.017 L/min. Once the mixing process begins, we will assume that the contents of the tank have an average S.G equal to 1.171, which remains constant throughout the mixing process. Assume perfect mixing; The density of water is 1000 kg/m'. Please calculate the following: a) The total mass of solution (g) in the tank after 2 hrs. b) The mass of NazSO4 (g) in the tank after 2 hrs. c) The concentration of NazSO4 (g/L) in the outlet stream after 2 hrs. onantram 625912 Nazsoy

Question
3) A very large tank of unknown volume, equipped with a double blade agitator is initially filled with 5.5
liters of an aqueous sodium sulfate (Na,SO,) solution having a concentration of 109 g NazSO4/L.
The specific gravity (S.G.) of the solution is 1.091. Into the tank, a solution having a concentration of
625 g NazSO4/L flows at a rate of 0.032 L/min. The S.G. of the inlet stream is 1.250. At the single
outlet to the tank, the flowrate is 0.017 L/min. Once the mixing process begins, we will assume that the
contents of the tank have an average S.G equal to 1.171, which remains constant throughout the mixing
process. Assume perfect mixing; The density of water is 1000 kg/m'. Please calculate the following:
a) The total mass of solution (g) in the tank after 2 hrs.
b) The mass of NazSO4 (g) in the tank after 2 hrs.
c) The concentration of NazSO4 (g/L) in the outlet stream after 2 hrs.
