Dear all,

I Would like to know the logical reasoning for temperature reduction during throttling process of saturated and superheated steam eventhough its enthalpy, meaning total energy of the system is constant? What is the science behind it. Thank you.

2.Most importantly,in wet steam throttling, drop in temperature is purely because of dryness quality rise, does that mean 100% dry steam throttling doesn't cause temperature drop??

3. Is it logical to consider the workdone by the steam as pressure reduction is taking place in throttling process?

As most of the throttling videos on YouTube taking workdone as zero, and trying to prove enthalphy as constant mathematically but the physical feeling is missing?

Kindly guide me.

Hi,

Let you consider these resources:

Note: Probably good to have a look at your thermodynamic textbook.

Good luck

Are you really still a student?

I am not student, I am working professional, since it is a basic question I have asked in this forum.

You can consult a Mollier diagram to learn.
