O le pa puipui lolovaia otometi hydrodynamic e aofia ai vaega e tolu: faavaa eleele, faataamilosaga laulau ma itu puipui faamaufaailoga vaega, lea e mafai ona vave faapipii i le faitotoa ma le ulufafo o fale lalo. O modules lata ane o loʻo faʻafesoʻotaʻi faʻapipiʻi, ma faʻapipiʻi paʻu paʻu i itu uma e lua e faʻamaufaʻailogaina lelei ma faʻafesoʻotaʻi le laulau lolovaia ma le puipui.
