A triple effect evaporator is supplied with saturated steam at 240 °F. The temperature at the last effect is 160 °F. The OHTCs are 250, 300, and 350 BTU/h ft². °F in the 1st, 2nd, and 3rd effects, respectively. If the total BPR in the three effects is 65 °F and the steam used is 9,000 lb/h, calculate the area of the evaporators in ft².
