| Abstract: | Looped sprinkler network is one of the important kinds of sprinkler irrigation systems. A new hydraulic analysis method used to determine flow rates, velocities and nodal heads of looped sprinkler network was proposed. The method was based on the energy balance equation, Hazen-Williams equation and nodal flow-pressure equation. The details including the mathematical model and the numerical simulation method were given. Numerical example demonstrated that the analytical procedure was simple and accurate. The method can be used to analyze not only looped sprinkler network, but also other complicated sprinkler irrigation system. |
