Claim 11:
12. A toilet, comprising:
an inlet structure configured to receive water;
a toilet bowl comprising a rim;
a split fluidly connected to the inlet structure, the split comprising a first passage and a second passage, the split dividing water flowing from a horizontal section into the first passage and the second passage;
a plurality of side channels connected to the second passage, the plurality of side channels including a first side channel and a second side channel, wherein the first side channel extends from the split downwardly around a first side of the toilet bowl, wherein the second side channel of the plurality of side channels extends from the split downwardly around a second side of the toilet bowl opposite the first side;
a shelf located below the rim and spaced apart from the rim, the rim and the shelf forming an inset channel that extends along a perimeter of the toilet bowl, wherein a height of the inset channel, between the rim and the shelf, decreases continuously in a single flow direction,
wherein the inset channel that extends along the perimeter of the toilet bowl is open to a waste receiving surface of the toilet bowl, and wherein a thickness of the rim increases so that a lower surface of the rim slopes downwardly toward the shelf so that a height of the inset channel, between the rim and the shelf, decreases in the single flow direction to reduce fluid losses in the single flow direction.
