The density of naoh solutions in water is given by the expression ( = 1.00 +1.06x, where is the density (g/cm') and x is the mass fraction naoh. two aqueous naoh feed streams are to be mixed continuously to form a 6 m (moles/liter) naoh product stream. the less concentrated feed stream is 8 mass%! naoh; the more concentrated feed stream has a measured density of 1.35 g/cm . if the desired volumetric flowrate of the product stream is 1000 l/hr, determine the volumetric flowrates of each of the feed streams. note for problem 2: this problem can best be worked by first converting all streams and compositions to a mass basis (i. e., mass flow rate, mass fractions). then it becomes a fairly straightforward material balance problem.
