Problem $12$

A $50wt\%$ acetic acid solution in water is supplied at a rate of $1,000k\frac{g}{h}$ to a unit to be

separated into two streams. The product stream contains acetic acid at $70wt\%.$ The

waste stream contains water at $70wt\%.$ The mass flow rate of the waste stream has a

value equal to $60\%$ of the value of the mass flow rate of the product stream. Find the

mass flow rates of the product and waste streams.
