It will be observed that the undershot wheel ismoved by the momentum of the water—the breast wheel and overshotwheel by its weight aided by its momentum. An overshot wheel willproduce twice the effect of an undershot wheel,—the dimensions, fall, andquantity of water being the same. The brea>t wheel is found to consumetwice the quantity of water required by an overshot wheel to do the samework. 340. In all water-wheeb the greatest mechanical effectis produced when the velocity of the water is 2J- timesthat of the wheel. 341. To find the horse power of a vertical water-wheel :— Let h ?=. breadth of stream in feet, d =z depth of stream,v=. mean velocity in feet of stream per minute, h =z height of fall,s =: weight of one cubic foot of water, and m = modulus of thewheel. mbdvsh Then horse power =330^ Example 412.—A water wheel is worked by a str
