一道关于化工的题目,但是是英文的,
Steam at 300℃,10bar,is used in an evaporator to conentrate a 30kg/min solution at 30℃.The solution is concentrated such that it leaves the evaporator at a rate of 20kg/min.the evaporation takes place at 2 bar pressure.Determine the amount of steam that is required if the steam leaves the system at a saturated liquid at 10 bar.
