derivation for special case for incompressible fluid; condition for v?
 
Hi friends,

I get stuck again :(

I have to work with the equation of state for a perfect gas and
continuity equation


I need the derivation for special case for incompressible fluid a condition for the velocity field.


Sry my english is not very good.
I did it like this but I know something is missing. I think I only took the continuity equation:

∂p/∂z=-p∙g→p=p_0-p∙g_z


I hope you can help me again

god bless you,
Simone
