Hello everyone,

I was reading in a document and I was watching in youtubethe following distinction: constant volume ans costant mass flow of the centrifugal compressors.
What is the distinctin? Or to put it differently what are the applications of constant volume flow and constanr mass flow to centrifugal compressors?

Hi,

A few documents for you to read and understand. 

Difficult to understand your query. The only thing valid is mass in = mass out =constant, nothing else. 

If P, T are changing during the compression process, Ro will change thus the volumetric flowrate.

Note: Don't be confused with standard condition.

Good luck.

Hi Breizh,

Thanks for the many documents.
I will share later the link with the information that I meant in my post. So, you can have a better idea!
