Leistungsbewertung von Minisprinklern
ISBN: 9786209542954 / Niemiecki / Miękka / 2026 / 76 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Für den Leistungstest wurden Minisprinkler von Rainport ausgewählt. Die Leistungsbewertung für Minisprinkler wurde für eine Höhe von 1 m durchgeführt. Der geschätzte Wert des Gleichmäßigkeitsfaktors lag für Minisprinkler im guten Bereich von 76 bis 91 Prozent. Der Gleichförmigkeitskoeffizient nimmt mit zunehmendem Abstand zwischen den Minisprinklern ab und mit zunehmendem Druck auf die Minisprinkler zu. Mit zunehmendem Abstand von 3 m x 3 m auf 7 m x 7 m nimmt die Gleichmäßigkeit der Verteilung für Minisprinkler von 89 % auf 81 % ab. Mit zunehmendem Druck von 1,5 kg/cm2 auf 2,0...

Évaluation des performances des mini-arroseurs
ISBN: 9786209548079 / Francuski / Miękka / 2026 / 72 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Les mini-arroseurs Rainport ont été sélectionnés pour le test de performance. L'évaluation des performances des mini-arroseurs a été réalisée à une hauteur de 1 m. La valeur estimée du coefficient d'uniformité s'est avérée satisfaisante, comprise entre 76 et 91 % pour les mini-arroseurs. Le coefficient d'uniformité diminue avec l'augmentation de l'espacement des mini-arroseurs et augmente avec l'augmentation de la pression des mini-arroseurs. Lorsque l'espacement passe de 3 m x 3 m à 7 m x 7 m, l'uniformité de la distribution diminue de 89 à 81 % pour les mini-arroseurs,...

Performance Evaluation of Microsprinklers for Varying Spacing and Head
ISBN: 9783659719516 / Angielski / Miękka / 2015 / 100 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Micro-sprinkler is one of the components used in micro irrigation system and its performance will have a major impact on success of system as a whole. It is therefore, necessary to test the micro-sprinkler so that the designer can select the micro sprinkler best suitable for a specific requirement and a system can be designed accordingly. Two different types of micro-sprinkler viz. type A (26 lph), type B (70 lph) were selected for the performance test. The performance evaluation for micro-sprinklers was carried out for operating pressure of 1.5 kg/cm2. The estimated value of uniformity...

GIS Based Modelling Of Surface And Groundwater Supplies
ISBN: 9783659666186 / Angielski / Miękka / 2015 / 168 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Conjunctive water use plan was developed by adopting the optimization and simulation approaches. The study area was divided into fifteen different land units based upon their source of irrigation using the Geographic Information System (GIS). Linear Programming technique was used for maximization of the net profit under the constraints of land, water, food, oil seed, cash crop and fodder requirements. The spatial optimization plan was developed for the study area for the kharif and the rabi seasons separately. In the simulation approach, various alternatives of conjunctive water use scenarios...

Performance Evaluation of Mini-sprinklers
ISBN: 9783659763564 / Angielski / Miękka / 2015 / 80 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Mini-sprinklers of Rain port were selected for the performance test. The performance evaluation for mini-sprinklers was carried out for height of 1m. The estimated value of uniformity coefficient was found to be in the good range of 76 to 91percent for mini-sprinkler. The uniformity coefficient decreases with increase in mini-sprinkler spacing and increases with increases in mini-sprinkler pressure. As spacing increases from 3m x 3 m to 7m x 7 m the distribution uniformity decreases from 89 to 81% for mini-sprinklers, respectively. As pressure increases from 1.5kg/cm2 to 2.0kg/cm2...

Response of cauliflower to various mulches and irrigation levels
ISBN: 9783659798191 / Angielski / Miękka / 2015 / 120 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The experimental field area was 540 m2 (30 m x 18 m). The experiment was arranged in Split-Plot Design with three irrigation levels (I1: 0.6 ETc, I2: 0.8 ETc and I3:1.0 ETc) in the main plots and mulching levels (M1: without mulch, M2: dry grass mulch, M3: silver mulch and M4: black polythene mulch) in the sub plots. Treatments were replicated four times. Each replication had twelve treatment combinations. The total depth of water applied in irrigation levels I1, I2 and I3 were 17.86 cm, 22.98 cm, and 28.09 cm, respectively. The maximum water saving (36.44 per cent) was achieved in irrigation...

Optimized Strategic Plan for Natuwadi Medium Irrigation Project
ISBN: 9783659791987 / Angielski / Miękka / 2015 / 112 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. A linear programming model was developed considering two specific objectives viz., net benefit maximization and optimal area allocation. Land available, water available, and food requirement are the constraints considered for model. The model was run at 70 per cent, 80 per cent, 90 per cent and 100 per cent availability levels of storage's excluding different water losses. The optimal cropping pattern indicated that net benefit and area are increased as water availability level increases. For Right bank canal of 965 ha ICA at 70 per cent, 80 per cent, 90 per cent and 100 per cent water...

Development of Rainfall IFD Relationship for Mulde
ISBN: 9783659770272 / Angielski / Miękka / 2015 / 72 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Rainfall intensity-duration-return period equations and nomographs on regional basis are required in the country for design of soil conservation and runoff disposal structures and for planning flood control projects. The significance of rainfall intensity-duration-return period analysis is also important from economic consideration. An over designed structure involves excessive cost and under designed structure will be unsafe and also involve high recurring in expenditure on repair, maintenance and replacement. An appropriate design would provide a structure with reasonable initial and...
