Abstract
A transition member (130) coupled between first and second slurry delivery devices (132, 134) for maintaining fluid slurry velocity therethrough is disclosed. Each slurry delivery device (132, 134) has a slurry passageway (144, 164) having a cross sectional area. The transition member (130) includes a transition passageway (200) operable to provide fluid communication between the slurry passageways (144, 164) of the slurry delivery devices (132, 134). The cross sectional area of at least a portion of the transition passageway (200) approximates the cross sectional area of the slurry passageways (144, 164) of the slurry delivery devices (132, 134). This allows the transition member (130) to maintain the fluid slurry velocity above the settling velocity of the slurry.
