A single-effect vertical evaporator concentrates 1.0 metric ton of 10% wt sucrose solution to 50% wt. The feed enters the evaporator at 20°C and has a specific heat of 1.0 BTU/lbm-°F. The evaporator is maintained at a vacuum of 600 mmHg against a barometric reading of 760 mmHg. The heat is provided by saturated steam at 8.8 kg/cm2 gauge. Calculate the weight of heating steam in kg needed for concentrating the sucrose solution.
