n: the result of a velocity traverse. When fluid flows in a pipe, the fluids velocity is not uniform owing to friction as the fluid moves past the pipes walls. With some measuring devices, it is important that the device be placed properly within the flow to obtain accurate measurement. Running a velocity traverse to obtain the profile is necessary to properly place the measuring device. See also velocity traverse. velocity safety valve n: see subsurface safety valve.

n: The distribution of velocity of all material point on the same section when fluid flowing.
