The diagonally-oriented flow channelhas a downstream portiondisposed downstream of the vertically-oriented flow channel, and an upstream portiondisposed upstream of the vertically-oriented flow channel. The downstream portionof the diagonally-oriented flow channelhas a cross-sectional areathat is greater than that of the upstream portion. The downstream portion's cross-sectional areais greater than the upstream portion's cross-sectional areaby an amount or percentage that is sufficient to slow fluid flow through the diagonally-oriented flow channel, so as to cause air within the fluid to rise and flow into the vertically-oriented flow channel
