I have little knowledge about computational fluid dynamics. I am trying
to model a straight tube, for which a fan is attached to one of the
tube and the other end is open.
Now my task is to calculate the pressure variation at the open end when
there is AIR FLOW change at the input.
I was able to calculate the steady state pressure drop delta P is
proportional to f *L * v^2/Diameter.
f - friction factor, L - length of the tube. v- fluid velocity.
But I need Pressure variation in time domain. How can i proceed.
