Temperature of hot gases flowing in a pipe is measured by a thermocouple inserted in the thermal well. The thermal well made of ______________ will facilitate the most accurate measurement of the temperature ?
Correct answer: A. Copper
- A. Copper
- B. Steel
- C. Aluminium
- D. Brass
Explanation
Copper conducts heat much better than steel, aluminium, or brass, so the thermal well reaches the gas temperature with less temperature lag and gives a more accurate thermocouple reading.
