The maximum heat transfer co-efficient from steam heating will be attained when the steam is_________________?
Correct answer: C. Saturated
- A. Supersaturated
- B. Wet
- C. Saturated
- D. None of these
Explanation
Saturated steam condenses directly at nearly constant temperature and releases its latent heat efficiently, giving a high film coefficient. Superheated steam must first be desuperheated, while wet steam introduces liquid-water effects that reduce the effective heating performance.
