(tûr′bĭn)
, Noun.
[L.
turbo
, -inis
, that which spins or whirls round, whirl.] 1.
A water wheel, commonly horizontal, variously constructed, but usually having a series of curved floats or buckets, against which the water acts by its impulse or reaction in flowing either outward from a central chamber, inward from an external casing, or from above downward, etc.; – also called
