When unsaturated air is adiabatically saturated, which of the following properties decrease? 1. Dry bulb temperature 2. Wet bulb temperature 3. Relative Humidity 4. Specific Humidity
When a mixture of air and water vapour is cooled at constant pressure upto saturation temperature of water vapour, the temperature attained is known as:
The temperature of air recorded by the thermometer, when it is not affected by the moisture present in it, is called
The dry bulb, wet bulb and dew point temperatures will all be same when the air is
Consider the following statements: 1. The relative humidity of air does not change with temperature as long as specific humidity remains constant. 2. Dew-point temperature is the temperature at which condensation begins when air is cooled at constant volume. 3. Saturated air passing over a water surface does not cause change of air temperature. 4. For saturated air, dry-bulb, wet-bulb and dew-point temperatures are identical. Which of the above statements are correct?
The wet bulb depression is zero, when relative humidity is equal to
Dew point temperature is the temperature at which condensation begins when the air is cooled at constant
