### Salt-Oil Mixture Separation Process A salt-oil mixture is to be sent to a washing unit to remove salt from the oil. - **Stream 1** contains the salt-oil mixture and is being fed to the washing unit at \( \dot{m}_1 \) kg/min with a salt mass fraction (\( x_{S,1} \)) of 0.05 kg\(_S\)/kg and the remainder is oil (\( x_{O,1} \)). - **Stream 2** is pure water (\( x_{W,2} \)) and is also being fed to the washing unit with a mass flow rate (\( \dot{m}_2 \)) of 200 kg/min. Two exit streams leave the washing unit: - **Stream 3** is a salt-water mixture with an unknown mass flow rate (\( \dot{m}_3 \)) and salt and water mass fractions (\( x_{S,3} \) and \( x_{W,3} \)) of 0.15 kg\(_S\)/kg and 0.85 kg\(_W\)/kg. - **Stream 4** is a salt-oil mixture. ### Objectives: 1. Determine the mass flow rate of Stream 3 (\( \dot{m}_3 \)). 2. Determine the mass flow rate of Stream 4 (\( \dot{m}_4 \)). 3. Find the mass fractions of salt and oil in Stream 4 (\( x_{S,4} \) and \( x_{O,4} \)). ### Assumptions: Assume a complete steady-state process. This explanation provides the basis for problem-solving involving mass balance in chemical engineering processes.
