Fresh orange juice contains 12% (by weight) solids and the rest water 90% of the fresh juice is sent to an evaporator to remove water and subsequently mixed with the remaining 10% of fresh juice. The resultant product contains 40% solids. The kg of water removed from 1 kg fresh juice is__________________?
Correct answer: D. 0.7
- A. 0.4
- B. 0.5
- C. 0.6
- D. 0.7
Explanation
The 1 kg feed contains 0.12 kg solids, which remain in the product. At 40% solids, the final product mass is 0.12/0.40 = 0.30 kg, so water removed is 1 - 0.30 = 0.70 kg.
