Ek states that ideal fluids an nonideal fluids react the same way to a change in radius/velocity/pressure, but the viscosity in the nonideal fluid causes a slight deviation from expected behavior.
They greatly stress that they are NOT opposite.
Im wonder how exactly this is possible.
With radius held constant:
Bernoullis equation (ideal fluids) says an increase in fluid velocity results in decreased pressure.
In Poiseuille (nonideal fluida) shows that an increase in fluid velocity causes increase in pressure.
Radius change also results in opposite results.
So....... Im not exactly sure what EK is saying. It seems pretty obviously clear that they are opposite....
