... because the normal pouring of liquid from any height over approximately 10 mm (0.4 in.) results in the rapid acceleration of the metal to speeds well above the danger speed of 0.5 m/s (20 in./s). In this case, the only way to prevent air and oxide entrainment is by constraining the metal within channels...
