An evaporator is fed continuously with 50,000 kg/h of a solution containing 10% NaOH, 10% NaCl, and the rest water by weight. During evaporation, water is removed as vapor and salt NaCl precipitates as crystals and is removed by filtration. The concentrated liquor leaving the evaporator contains 50% NaOH, 2% NaCl, and the rest water. Calculate: a) the mass of water evaporated per hour b) the mass of salt precipitated per hour c) the mass of concentrated liquor produced per hour
