Abstract

Water shortage and high energy cost have promoted the concept of a trail tube irrigation system. Trail tubes are perforated polyethylene hoses, which can be used to replace sprinklers on a center pivot irrigation system for water and energy conservation. A theory on the hydraulics of catenary trail tubes was developed by Chu (1986). The purpose of this study was to evaluate the catenary trail tube theory under laboratory conditions. Perforation flow rate, elevation and pressure were measured on three trail tubes in the laboratory. Tube flow rate, velocity head and friction loss along the tube were calculated from measured data. Comparisons of laboratory data with theoretical values indicate that the theory is adequate for the design of catenary tube irrigation systems.
