Abstract
Abstract Apparatus for receiving a flow of water under pressure and for projecting the water through the air in the form of a jet having improved uniformity of cross section, power concentration and range of projection. Means is provided for manually or automatically rotating the apparatus to permit horizontal, fullcircle, angular projection of the water jet and for optionally adjusting the vertical elevation of the water jet trajectory. The range of water jet projection may be lengthened by injection of a friction-reducing chemical fluid to the water flow through the apparatus or may be shortened by selectively placing a mechanical deflection means at least partially across the water jet issuing from the apparatus. Automatic timer sequence means is optionally used to cyclically change the range of projection and the rate of rotation of the apparatus to achieve sequential irrigation of two or more areas of land within the range of coverage of the water jet and to permit uniform irrigation of relatively rectangular land areas. Means responsive to wind pressure and direction is provided to control power concentration and the arc of trajectory of the water jet.

A method of forming a jet stream comprising: directing a pressurized flow of water through a cylindrical region whose boundary provides a frictional resistance to the flow; projecting the flow outwardly of the region as the stream is reduced in cross section and forms a substantially turbulence-free stream of uniform cross section; selectively injecting a frictionreducing agent into said flow to minimize the frictional force between said boundary and said flow; rotating the region about a generally vertical axis when the region is inclined relative thereto; sensing a wind force adjacent to said region as the latter rotates about said axis; and changing the angle of inclination of said region as a function of the sensing of said wind force and in response to the flow of water through said region.
