最佳解答:

m1(kg) : (added) sugar solids flow m2(kg) : (removed) water flow m3(kg) :final product flow overall mass balance: 2000=m1+m2+m3 (1) product solid balance: 2000*0.1=m3*0.15 (2) sugar balance: m1=m3*0.15 (3) solve equation (1)(2)(3) simultaneously you can obtain m1=200 m2=467 m3=1333 so the quantity of final product is 1333(kg) with 200(kg)sugar added and 467(kg) water removed

其他解答:

請問overall 是不是應該改這樣 2000+m1= m2+m3 因為sugar也是進去系統的ㄧ個( liquid 也是進去系統)6FE6251C5F3F8A0F
