 It is a need to generate a 42% wt NaOH solution

It is a need to generate a 42% wt NaOH solution by initially dissolving solid NaOH (F1) with H20 (F2) to yield 62% wt NaOH solution in a dissolution tank (DST). After a complete process of dissolution in the tank, the solution is subsequently fed to a dilution tank (DLT) where more H2O is added to generate the final solution containing 42% wt NaOH. This H2O was acquired from a bypass (B) stream and which as a fraction of the H20 (W) fed to the process. To generate 55 lbs of the 42% wt NaOH solution, calculate the quantity of the following streams: B, bypass stream F1, solid NaOH F2, water fed to the DST M, feed to the DLT W, water fed to the process
