I thought this definition of "fully developed flow" may change with the temperature gradient and concentration gradient between the fluid and pipe wall. Otherwise, it should be defined as follows.
"Except the pressure gradient in the pipe section (which balances shear resistance to sustain...
Does the definition of fully developed flow is different for laminar and turbulent?
I understand the fact that the entrance length are different in laminar and turbulent flows, but I believe the definition of fully hydrodynamically developed flow means that the velocity profile (hence momentum)...
