Abstract

The purpose of this study provide water and energy by designing two
trickle irrigation systems with compensating emitters(Katif) which have
constant discharge with different pressure on zero slope fields based on
manufacturing and hydraulic variations. The experiments were carried out in
Department of Agricultural Engineering Laboratory and Collage Farm of
Faculty of Agriculture in Menoufia University during 2018.
The experiments is based on flow variation of total allowable head
loss for lateral by sitting a pressure regulator at the beginning of each lateral.
Also based on the emission uniformity that dependent on the coefficient of
variation of lateral.
A manufacturing coefficient of variation was showed based on lab test
by testing three emitters 2 , 4 and 8 l/h at inlet pressure 0.5, 1, 1.5 and 2 L/h.
A total, CVt was determined in turn of calculating system uniformity. A field
experiment was conducted for 50 m and 75 m of lateral length at zero slope
for mm inner diameter and 16 mm outer diameter. In addition, spacing
between emitters (2 m) with compensating emitters (Katif) under three
different emitter flow rates (2, 4 and 8 L/h) for compensating emitters (katif)
at inlet pressures one and 1.5 bar.
Friction loss was measured along lateral line and compared to the
calculated one. The coefficient of variation of emitter flow rate was found
for 50 m and 75 m of drip lateral line on zero slope.
Evaluations high lighting the effects of design choices in terms of
energy saving, comparisons between optimal lateral lengths and analysis of
lateral pressure heads variability are carried out.
