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.
