Which of the following commonly used condenser tube materials has the lowest thermal conductivity ?
Correct answer: A. Stainless steel
- A. Stainless steel
- B. Admiralty brass
- C. Aluminium brass
- D. Titanium
Explanation
Stainless steel has much lower thermal conductivity than admiralty brass, aluminium brass and titanium, so it offers the greatest resistance to heat flow among these condenser-tube materials.
