An insulated tank, open to the atmosphere, contains 1500 (lbm) of 40 wt % sulfuric acid at 60 (degrees F). It is heated to 180 (degrees F) by injection of live saturated steam at 1 (atm), which fully condenses in the process. How much steam is required, and what is the final concentration of H2So4 in the tank?

A closed, rigid steel tank contains 1 lbm of water, initially at 260 F and a quality of 60%. The tank is fitted with a paddle wheel and the water is stirred until the temperature is 350 F. The tank is well insulated on the outside and the steel is in thermal equilibrium with the water. The mass of the steel tank itself (not including water) is 60 lbm and the specific heat of the tank is 0.115 Btu/lbm·R. Changes...
