11. Provided that Um is not too large, this velocity profile is stable to hydrodynamic perturbations. 12. Depth migration begins with time data converted to depth data by a spatial geological velocity profile . 13. Velocity profile of the Herschel Bulkley fluid for various flow indices " n ".14. We can see in this image the developing velocity profile of a fluid entering a pipe. 15. A developed velocity profile in a duct that shows why polished surfaces have little effect on flow. 16. In this region the velocity profile develops and thus the flow is called the hydrodynamically developing flow. 17. The velocity profile is an equation to calculate the velocity based on a specific location in the flow. 18. The velocity profile will be non-uniform due to friction between the annulus wall and the fluid. 19. The fuller velocity profile of the turbulent boundary layer allows it to sustain the adverse pressure gradient without separating. 20. For all but the simplest of velocity profiles U, numerical or asymptotic methods are required to calculate solutions.
