Loss of heat from untagged steam pipe to the ambient air is by __________________?
Correct answer: D. All A., B. & C.
- A. Conduction
- B. Convection
- C. Radiation
- D. All A., B. & C.
Explanation
Heat travels through the pipe wall by conduction, leaves the outer surface by convection to the air, and is also emitted by radiation. Since the pipe is unlagged, all three modes contribute to the heat loss.
