Dry bulb temperature increases.
Specific Humidity decreases.
Dew point temp decreases.
Relative humidity decreases.
Enthalpy and wet bulb temp remain constant.
So, Sp. Volume increases.
Specific Humidity decreases.
Dew point temp decreases.
Relative humidity decreases.
Enthalpy and wet bulb temp remain constant.
So, Sp. Volume increases.

In chemical dehumidification, chemical-like salt is spread in the stream of air which absorbs water vapour but the temperature difference caused cannot be controlled.

Option D is correct.
By tracing the line of de-humidification on Psychometric chart. It is clear that;
1) Wet Bulb Temperature DECREASES.
2) DEW Point Temperature DECREASES.
As for dehumidification, some amount of vapours condenses, giving out energy in the heat which raises the sensible temperature!
So, Option D is correct

In chemical dehumidification process WBT will remain constant.

Chemical dehumidification takes place along constant enthalpy line i.e WBT line. Hence, WBT remains constant while DBT, DPT and specific humidity decrease.

D. Is correct because chemical dehumidification process is a inclined downward line with increasing DBT.
