Sprinkler irrigation methods are widely preferred, where labor is expensive,
because they require less labor. Semi-portable and fully fixed systems are
preferred more and more in nowadays, because labor costs are constantly
Main components such as pipelines, and sprinkler heads of sprinkler
irrigation systems have been significantly changed recently. The cost has
been lowered, and the system has become practical thus, their use is
generalized. Sprinkler heads are of greatest importance in sprinkler irrigation
system. High capacity sprinkler heads (Big Guns) with high wetting capacity
are widely preferred. These are very good at medium and high operating
pressures. Low pressure applications may damage delicate plants. Nozzle
diameters of medium size sprinkler heads are ranged between 8 to 12mm,
and their wetting diameters between 15 to 25 mm. Such heads are widely
used in the irrigation of field crops, vegetable gardens and orchards. Nozzle
diameters of large size sprinkler heads can be ranged between 12 to 28mm,
and wetting diameter between 25 to 55mm. Such heads are mainly used in
the irrigation of field crops by medium and large sized enterprises.
Operating pressure is the pressure required at the nozzle. Losses due to
leakage and friction can be controlled by calculating the pressure differences
between the manometers at the pump outlet and the distant sprinkler head.
Valves can be installed at the beginnings of lateral pipelines, in systems the
main pipelines, of which are embedded in the ground. In addition to these,
connection pieces such as T, bend, reduction, and pipe stopper are also
used. Saving energy or using more sprinkler heads with the same energy is
possible by using pipes with the largest possible diameters, minimizing
