Hydraulics of microtube emitters in a drip irrigation system

Abstract

Studios were conducted on the hydraulics of microtube emitters in a drip irriga tion system. The relationships between the parameters, viz., pressure head II, length L, diameter D and discharge Q were estimated for combined and individual flow conditions, viz., laminar, transition and turbulent, by fitting multiple log-linear regression equations. Minor loss coefficients were obtained and the friction loss equations established. Equations similar to Blasius and general equations were developed for friction factor in turbulent and laminar regions.
