Pure water is used to dilute 152 lbm of a sulfuric acid stream that has an initial mass fraction of H2SO4 equal to 0.85 in order to produce a diluted acid with an H₂504 mass fraction of 0.45. The temperature of the water is 40 °F and that of the concentrated acid is 77°F. An enthalpy-composition diagram for the system is shown below.
