Hello,

 

I was working on the general energy equation for some thermodynamics calculations like of compressors and I found an article on web. I think it is taken from a book. I also downloaded it to the attachments section.

 

On equations 12-21 and 12-22, it says even for incompressible flows, the u2-u1 = qnet if there is no friction loss.

Yet, I could not understand how it is possible. For example if a compressor compresses a stream adiabatically, the internal energy will increase a lot and qnet will equal to 0.

So how it is possible ? Is the case article mentioned is only true for incompressible flows ?

Thank you.
