Abstract Filtering is an important measure for the prevention of emitter clogging in micro-irrigation systems. Head loss and energy consumption are two problems pressurized irrigation Therefore, a combined filtration device – micro-pressure filtering washing tank was designed. In this study, taken as research object, physical model test inlet flow sediment concentration carried out. The head pr...

The rapid proliferation of fertigation in modern agriculture has brought about a growing demand for factory mixed fertilizer solutions, as well as wide-scale dissolution of solid fertilizers by farmers in the field. Rules of chemistry and physics control the rate of dissolution and, hence, the nutrient content in the fertilizer solution. Potassium chloride (KCl) is the cheapest potassium-contai...

INTRODUCTION Occasionally, urologists may see patients requiring temporary bladder irrigation at hospitals without stocks of specialist irrigation apparatus. One option is to transfer the patient to a urology ward, but often there are outstanding medical issues that require continued specialist input. Here, we describe an improved system for delivering temporary bladder irrigation by utilizing ...

The paper deals with calibration of the simulation models of hydraulic part of an irrigation project. Calibrated simulation model can be used in design, reconstruction, enlargement or maintenance of the pressurized irrigation systems. Computer model of the water distribution system is a valuable tool which can assist engineers and planners in analyzing the hydraulic performance of water deliver...

Climate change that occurs requires secondary irrigation, to meet water needs by plants from existing sources (springs, or irrigation. This study aims see the effect of irrigation on increasing production shallot bulbs Lansuna variety. The was conducted in dry season 2017 Minahasa Regency. layout experiment used a Randomized Block Design 2 treatment with 5 replications per plot measuring 4m x 4...

Pressurized irrigation systems have gained more attention lately, among other alternatives, in Mediterranean countries. Since the initial investment costs of pressurized are quite high, it is crucial to determine design parameters such as pipe diameter. Most current optimization techniques for diameter selection based on linear, non-linear, and dynamic programming models. The ultimate aim these...
