sel to be symmetrical with respect to theaxis of the jet, as in Fig. 119, then by symmetry there can be no resultantforce on the vessel in a direction perpendicular to the axis of the jet.Therefore we need to consider only the change in. momentum along theaxis. Let m be the mass of water delivered… … where A is the area of the cross-section of the jet and Wi is the weight ofa cubic foot of water. Replacing the various magnitudes by their nu-merical values we obtain . ^^■^T3X-(^4^0x(«»£.)x(^ + ^-60°) 32 ft.sec.^ = 102.3 lb. Discussion. — It is evident from the general expression of F that its…
