I tried modelling a simple Fluid network with a local resistance:
The local resistance uses "By loss coefficient vs. Re table" as model parameterization and the loss coefficient is set to 1.5 for every Re-Number
The resistance area is set to be the cross sectional area of a pipe with a diameter of 0.02m.
To better understand what happens I tried to calculate the same by hand and see if I can come up with the same result:
In this case there is p1=0, u1=0, h2=0 and p2=0. So the equation simplifies to:
With the cross sectional area of the pipe results the Volumetric Flow of the System.
My Problem here is that the measured Volumetric flow is not equal to my calculated value.
The matlab code I used is attached.
What am I doing wrong?
Thanks in advance!
