Design and Manufacture of Pottery Dripper for the Use of Saline Water in Irrigation Systems

Abstract

The pottery dripper dimensions are designed and Manufactured in three volumes (49, 31.4 and 16.5 cm 3), three nominal porosity (10 , 21 and 31%); then various types of pottery drippers (PD) are tested under three pressure heads (1, 0.75 and 0.5 bar) and three concentrations of saline groundwater (6154, 7149 and 7154 ppm), from Ras-Sudr Research Station. The main results of this study showed the following: For porosity P1 (10%) of pottery dripper, under operating pressure head 1 bar, the discharge ranged from 0.5 l/s to 1.14 l/s; under operating pressure head 0.75 bar, the discharge ranged from 0.5 l/s to 1.14 l/s; and under operating pressure head 0.5 bar, the discharge ranged from 0.2 l/s to 0.53 l/s. For porosity P2 (21%) of pottery dripper, under operating pressure head 1 bar, the discharge ranged from 1.69 l/s to 4.11 l/s; under operating pressure head 0.75 bar, the discharge ranged from 1.14 l/s to 3.06 l/s; and under operating pressure head 0.5 bar, the discharge ranged from 0.58 l/s to 1.82 l/s. For porosity P3 (31%) of PD, under operating pressure head 1 bar, the discharge ranged from 24.1/s to 37.7 l/s; under operating pressure head 0.75 bar, the discharge ranged from 16.8 l/s to 28.3 l/s; and under operating pressure head 0.5 bar, the discharge ranged from 9.5/s to 19.4 l/s. Saline water concentration decreased from 6154 ppm to 5840, 5806 and 5440ppm using the PD with porosity 10, 21 and 31% respectively. Saline water concentration decreased from 7149ppm to 7106, 7013 and 6979 ppm using the PD with porosity 10, 21 and 31%, respectively; and finally saline water concentration decreased from 7863 ppm to 7846, 7778 and 7285 ppm using the PD with porosity 10, 21 and 31 % respectively,
