With reference to Wet bulb temperature, consider the following statements: 1. It is the temperature of adiabatic saturation.2. The wet bulb temperature is always lower than the dry bulb temperature but will be identical with 100% relative humidity.Which of the statements given above is/are correct? |ForumIAS

[A] 1 only

[B] .2 only

[C] Both 1 and 2

[D] Neither 1 nor 2

Answer: C

Notes:

Statement 1 is correct: The Wet Bulb temperature is the temperature of adiabatic saturation. This is the temperature indicated by a moistened thermometer bulb exposed to the air flow.
Statement 2 is correct: The wet bulb temperature is always lower than the dry bulb temperature but will be identical with 100% relative humidity (the air is at the saturation line). A wet-bulb temperature of 31°C is exceedingly harmful to humans, while a temperature of 35°C is unsurvivable for more than 6 hours.
