The wet bulb and dry bulb temperatures of an air sample will be equal when : 1. Air is fully saturated 2. Dew point temperature is reached 3. Partial pressure of vapour equals the total pressure 4. Humidity ratio is 100% Which of the above statements are correct?(a) 1 and 2 (b) 2 and 3 (c) 3 and 4 (d) 1 and 4 |

Answer» (a) 1 and 2 • The WBT and DBT and Dew point temperature all are equal at saturation curve i.e. RH = 100% of psychrometric chart • It is impossible that vapour pressure is equal to total pressure in air-vapour mixture • Humidity ratio of 100% has no meaning in psychrometry |
