Consider the following statements regarding the throttling process of wet steam:
1. The steam pressure and temperature decrease but enthalpy remains constant
2. The steam pressure decreases, the temperature increases but entropy remains constant
3. The entropy, specific volume, and dryness frication increases
4. The entropy increases but the volume and dryness fraction decreases.
Which of the above statements are correct?
Option (A)
1 and 4
Option (B)
2 and 3
1 and 4
2 and 4
Correct Option:
Question Solution:

Enthalpy remain constant, entropy increases. Specific volume in increases temperature decreases.
