Brass tubes are used in the manufacture of tubes of evaporators used in sugar and salt industries, mainly because of its ______________________?
Correct answer: C. High corrosion resistance
- A. High co-efficient of thermal expansion
- B. Low thermal conductivity
- C. High corrosion resistance
- D. All A., B. and C.
Explanation
Brass is selected for these evaporator tubes mainly because it resists corrosion in the sugar and salt environments. Its thermal conductivity is not low, so option B is not a valid reason and “all” cannot be correct.
