A mass of 500 lbm of 40 wt % sulfuric acid solution at 140°F is diluted with 200 lbm of pure water at 100°F.
A) What is the concentration of the resulting solution?
B) What is the heat effect (Q) of this mixing if the mixing is done such that the resulting solution is at 100°F?
C) If the mixing was done adiabatically, what would be the resulting solution temperature?
A) Find the mass of sulfuric acid in the original solution before it is diluted:
0.4(500 lbm)=200 lbm
