What is the yield of sodium acetate crystals (CH3COONa•3H2O) obtainable from a vacuum crystallizer operating at 1.33 kN/m2 when it is supplied with 0.56 kg/s of a 40% aqueous solution of the salt at 353 K. The boiling point elevation of the solution is 11.5 K. DATA: ΔHC = 144 kJ/kg trihydrate CP of solution = 3.5 kJ/kg-K
