Can Flow of Fluids Premium
handle compressible gases as well as liquids? |
|
Flow of Fluids Premium uses the Darcy-Weisbach method
for calculating the pressure drop in a pipeline. This
method assumes the density of the fluid is constant in
the pipeline. The Crane Technical Paper 410 states that
the Darcy-Weisbach method provides satisfactory results
under the following conditions: |
|
If the calculated pressure drop is less than 10% of the
inlet pressure, then reasonable accuracy will be
obtained if the density used for the fluid is based upon
either the upstream or the downstream conditions. |
|
If the calculated pressure drop is greater than 10%, but
less than 40% of inlet pressure, reasonable accuracy can
be achieved using the density based on the average of
the upstream and downstream conditions. |
|
For pressure drops larger than 40%, use a method that
incorporates the compressibility of the gas. |
|
Using the above guidelines Flow of Fluids Premium can
provide accurate results for gas distribution systems
found in plants and buildings. |
