indeed, at 1/4" it seems a bit risky letting only the lower half do the work.

to take this to a more theoretic level. one can easily calculate the surface where the water enters the block at the nozzle (circular). one can also easily calculate the total surfaces where the water can evacuate to the exits points (small rectangles)

if i follow bill's line of thought, it would be better to design it that the evacuating water has a narrower total surface, than the total surface of entry.

what would be the best tradeoff. a jet effect in the hosebarb. or a larger hosebarb with multiple small jets inside the waterblock. (i feel again, that i will prolly be the only one understanding this mumbo jumbo)
