Effect of distributor on flow rate in a drip irrigation system

Abstract

The effect of distributor on flow rate was studied. For each diameter of microtube, different length combinations of inlet tubes and drippers were tried. It was found that the discharge rate from the system with the distributor was higher than that of microtube having the same length and size. The frictional losses, the combined minor losses and distributor losses for different flow conditions were estimated. From the observed data, a few combinations which satisfied the requirements, viz., length, discharge and pressure head were selected to use as a guideline for design of the KAU drip irrigation system.
