Webis limiting the flow velocity to a so-called “erosional velocity,” under which it is assumed that no erosion-corrosion would occur. Over the last 40 years, the American Petroleum Institute recommended practice 14E (API RP 14E) equation has been used by many operators to estimate the erosional velocity. The Webvelocity, Vdl, or, less accurately, the critical velocity. Slurry flow at velocities above the deposition-limit value is free of a stationary deposition. 3.2.3 Minimum velocity The mean slurry velocity at which the least energy is dissipated in slurry flow is called the minimum velocity, Vmin.
