portlonal to the Distance to which theFluid will spout from an Adjutage at H;For the Vdocity will be as the Square Rootof A H, and the Time as the Square Rootof H K; whence the Product of these twowill express both the Space pass’d over bythe projected Body, and also the Line H I,as is well known to Geometricians.

Hence it follows, that a Fluid willspoutfrom a Hole or Adjutage D in the Centre ofthe Semicircle , or middle Point of the AltitudeA K, to the greases horizontal Diftance K Mpossible ; because the Perpendicular F D isthe greatest that can be drawn to the Di-ameter A K. Also ’tis evident, that fromtwo Holes B and H, equally difiant above andbelow the middle Altitude D, the Jets of Wa-ter will be made to the fame horizontal in s-tance K N ; because the Perpendiculars tothese two Points, viz. C B and IH, areequal.

Moreover,, the horizontal DistanceKM, to which the Water spouts from Vthe Centre, is equal to the Diameter orAltitude A K, or twice D F. For sincethe Velocity of the Jet at is equal tothat acquired by falling through the HeightAD, or DK, it will, as being uniform,carry the Fluid in an horizontal Direction
