Question: A batch of fuel-cell electrolyte is to be made by mixing two streams in large stirred tank. Stream 1 contains a water solution of H2SO4 and K2SO4 in mass fractions XA and xgl lbm/lbm of solution, respectively (A = H2SO4, B = K2SO4). Stream 2 is a solution of H2SO4 in water having a mass fraction XA2.
If the tank is initially empty, the drain is closed, and the streams are fed at steady rates w1 and w2 lbm of solutionlhr, show that XA is independent of time and find the total mass m at any time
