A single-effect evaporator concentrates a 20-wt-% aqueous solution of H2SO4 to 70%. The feed rate is 25(lbm)(s)-1, and the feed temperature is 80(°F). The evaporator is maintained at an absolute pressure of 1,5(psia), at which pressure the boiling point of 70-% H2SO4 is 217(°F). What is the heat-transfer rate in the evaporator?
