Question

Answer

Pure dehumidification is achieved by passing air through the spray water which is maintained at dew point temperature. By doing this, excess moisture condenses and temperature remains constant.

Answer

At DPT water vapour condesed means comes out of air.. means automatically dehumidification occure

Answer

To achieve pure dehumidification, air is passed through spray water maintained at the dew point temperature. This process effectively removes moisture from the air, resulting in a lower humidity level.

Here is a detailed explanation of each option:

a) DBT (Dry Bulb Temperature): The dry bulb temperature refers to the temperature of the air without considering the moisture content. While passing air through spray water at the dry bulb temperature can lead to some level of dehumidification, it may not achieve pure dehumidification. This is because the dry bulb temperature does not take into account the moisture present in the air.

b) WBT (Wet Bulb Temperature): The wet bulb temperature is the temperature of the air when water evaporates from a wet surface, such as a water-soaked wick. While passing air through spray water at the wet bulb temperature can help in dehumidification, it may not achieve pure dehumidification. The wet bulb temperature is influenced by both the temperature and humidity of the air, but it does not directly indicate the moisture content.

c) Dew Point Temperature: The dew point temperature is the temperature at which the air becomes saturated and condensation occurs. By passing air through spray water maintained at the dew point temperature, pure dehumidification can be achieved. When the air is cooled to the dew point temperature, the moisture in the air condenses and is removed, resulting in a lower humidity level. This method ensures that the air reaches its saturation point and eliminates moisture effectively.

Therefore, option 'C' is correct because passing air through spray water maintained at the dew point temperature is the most effective method to achieve pure dehumidification. It ensures that the air is cooled to the point where condensation occurs, removing moisture and reducing the humidity level.
