Irrigation systems are well known for their low efficiencies. Microirrigation
system is becoming popular even in humid areas because of the many advantages it
offers. Microirrigation is really the first irrigation method that can potentially maximize
productivity while conserving soil, water and fertilizer resources and simultaneously
protecting the environment. Since a micro irrigation system can achieve very high
application efficiency, it should be further explored even for supplemental irrigation in a
high-rainfall tropical country like Malaysia, with annual rainfall exceeding 2500mm.
Porous pipe is useful both for surface and subsurface micro irrigation systems
and it can be used in a variety of ways to meet any irrigation need. However very little
information is available about the discharge uniformity, operating characteristics and the
moisture distribution pattern of porous pipe irrigation laterals. This research work on the hydraulics of two types of porous pipe was carried out to determine such
performance criteria as the pressure-discharge relationship, pressure headloss, friction
factor Reynolds number relationship and water dispersion in the soil. The water
distribution pattern was observed in a soil box. Several lengths of imported porous pipes
were subjected to various upstream pressure inputs to determine the average discharge
along the lateral and the associated pressure losses. |
