flow trough a centrifugal compressor
flow trough a centrifugal compressor
(OP)
Hello,
I'm looking for an equation which shows a relation between the fact that when the density of air becomes larger the flow through a centrifugal compressor increases
For example: the flow increases with a factor 1.15 from 35°C to 5°C.
This is with constant pressure of the compressor
Thanks a lot

RE: flow trough a centrifugal compressor
I would assume that the could remain constant (if the compressor had the required duty - then when desity increased of course mass flow would go up.
for air 35 deg C to 5 deg C corresponds to an increase in desity of (273.15+5)/(273.15+35)=11% other gasses may see a larger density increaes at the mentioned temperature drop.

RE: flow trough a centrifugal compressor
Now I want to know the relation that the flow through the compressor becomes greater because of an increase of density.
The reason is because the compressor compresses the same volume but with a bigger density.
