| Abstract | ||||
| Irrigation using the perforated pipes system is a way for furrow and border irrigation, and it has been perhaps one of the simplest and most effective ways of improving the flexibility and efficiency of water supplies. The main objective of this work is to study the possibility of utilizing plastic microfilm as a perforated tube for irrigation. Also, studying some factors that affect water uniformity distribution along perforated plastic microfilm tubes (PPMT). Plastic microfilm tubes with different diameters of 190, 254, and 320 mm were investigated to use as perforated tubes for irrigation with orifices diameters of 20, 40, 60, and 80 mm. The obtained results of the tube diameter of 190 mm generally showed that the pressure head dropped gradually in the perforated plastic microfilm tube and this dropping trend ended after that increased gradually until the tube ended. The pressure head variation (Hvar) along the tube was about 31.25% and 25.81 % for orifices diameters of 20, and 40 mm, respectively. The actual discharge (Qact) of the orifices were closely varied along the tube length. Meanwhile, the theoretical discharge (Qth) dropped gradually in the tube. The discharge variation (Qvar) along the tube was about 40.49% and 12.06% for orifices diameters of 20, and 40 mm, respectively. The pressure head variation value ranged from 25.81 to 64.71% and the discharge variation ranged from 12.06 to 58.66% for investigation conditions. | ||||
