Question

If the wet bulb temperature of air at a particular place in a mine is \(31^\circ\mathrm{C}\), then the velocity of air in that place should be

• A. More than \(1\ \mathrm{m/s}\)
• B. Less than \(1\ \mathrm{m/s}\)
• C. More than \(2\ \mathrm{m/s}\)
• D. Less than \(2\ \mathrm{m/s}\)

Hint:

Higher wet bulb temperatures require \[ \boxed{\text{Higher air velocity}} \] to maintain acceptable working conditions in underground mines.

Answer 1

The Correct Option is A
