Problem #$1$: $(15)$

A nitrating process contains a waste stream of $HN{O}_{3}23\%,H_{2}S{O}_{4}54\%$ and $H_{2}O23\%$ by weight. This acid is entering another process to be concentrated. A final stream has contained $26\%HN{O}_3,60\%H_{2}S{O}_4$ by the addition of a solution of $92\%HN{O}_3$ and another stream with pure $H_{2}S{O}_4.$ Calculate all streams and give the "default" table of the stream leaving the process; that must be $1200kg$ of desired mixture.
