Question

Which of the following properties decrease during chemical dehumidification?

1. Relative humidity	2. Wet bulb depression
3. Specific volume	4. DPT

• A. 2, 3 and 4
• B. 1 and 4
• C. 1, 2 and 4
• D. 2 and 4

Answer 1

The correct option is B 1 and 4


$R{H}_2<R{H}_1$

${\omega }_2<{\omega }_1$

Since,
$\omega \propto DPT$

So,
$DPT2<DP{T}_1$

$v_2>v_1$

WBD = DBT - WBT

Since,
$DB{T}_2>DB{T}_1$

So,
$WB{D}_2>WB{D}_1$
