n: the rate at which mud is travelling in the annular space of a drilling well.

n: The linear velocity of a fluid passing through an annular space. The term critical annular velocity is often used to describe the flow rate or velocity at which entrained solids will be efficiently transported by the annular fluid. If the fluid velocity f

the velocity of fluids flowing in the annulus. Important in clean-up and displacement processes.
