Download or read book Practical Two stage Pipe Expansions for Centrifugal Pump Irrigation written by John A. Fazio and published by . This book was released on 1989 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Centrifugal irrigation pumps discharge fluids at high velocities that must be slowed to minimize energy losses due to friction. Pipe expansions make the transition to larger pipes associated with slower velocities. Expansions convert the upstream velocity head to static head in the downstream pipe. The transition to a larger pipe is commonly an abrupt or single-stage conical pipe expansion. Two-stage conical pipe expansions have been shown to be more efficient and a potential alternative. Four two-stage pipe expansions using standardly available materials were constructed and tested at common irrigation flow rates. These expansions require less space and cost less than optimum two-stage expansions. Pressure change across the pipe expansions were measured. The calculated head loss coefficients were compared to published values of abrupt, single-stage, and optimum two-stage pipe expansions. Head loss coefficients for the 50 - 100 mm and 75 - 150 mm two-stage expansions averaged 0.32 and 0.28 respectively. Loss coefficients for the 100 - 200 mm and 125 - 250 rim two-stage expansions averaged 0.16 and 0.17 respectively. The two-stage expansions operated more efficiently than abrupt and single-stage expansions and were economically practical for many pumping situations. The 50 - 100 mm two-stage expansion was only a slight improvement over a single-stage welding cone expansion. The fitting was economical as electricity prices rose over $0.05/kWh for crops requiring 3000 annual operating hours. The larger fittings became progressively better. The 75 - 150 mm expansion became economically practical at $0.03/kWh when operating more than 1,600 hours. The 100 - 200 mm and 125 - 250 mm two-stage fittings were always practical. Beginning with the 75 - 150 mm size and increasingly with the next two larger sizes, optimum two-stage fittings became economically competitive. Optimum two-stage expansions operated most efficiently, but because of their high cost were only practical for high electricity costs and long irrigation seasons. The three largest two-stage expansions tested are improvements over abrupt or single-stage expansions when constructing a pump discharge. Replacing an existing, less efficient expansion may not be cost effective because the existing fitting cost is lost. While only a small part of an irrigation system, these two-stage expansions can improve system performance with little extra cost and without requiring difficult to obtain components.

Download or read book Irrigation System and pump selection written by Jennifer Laffan and published by NSW Agriculture. This book was released on 2015-06-30 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has two parts. Part 1 will help you choose the irrigation system that is right for you, and Part 2 will help you select, operate and maintain your pumping equipment. Part 1 If you are installing or upgrading an irrigation system you will probably be seeking to increase production, decrease the amount of water used or reduce labour required. Part one of this book is about selecting the irrigation system that is best for your enterprise. It is an overview of: · the most widely used irrigation methods in NSW · the capabilities and limitations of the most widely used irrigation methods in NSW · the major issues to consider when selecting an irrigation system · the basic financial analysis you can use to determine the viability of a system you are considering. Part 2 You can save money by increasing productivity and efficiency of your irrigation system if you can improve the performance of the pump. This section about the features of common irrigation pumps helps you to select, operate and maintain your pumping equipment. It contains information on pump types, duty, curves and selection. It contains an explanation of: · the common types of pumps for irrigation systems · pumping head components: static head; suction head; velocity head; friction loss · manufacturers’ pump curves · maintenance and troubleshooting procedures for pumps. This publication was produced by Education Delivery, Tocal College. It supports the following competencies from National Training Package AHC10 Agriculture, Horticulture, Conservation and Land Management: AHCIRG306A - Troubleshoot irrigation systems, AHCIRG402A – Determine hydraulic parameters for an irrigation system, AHCIRG410A - Select and manage pumping systems for irrigation

Download or read book Sprinkler and Drip Irrigation written by V. Ravikumar and published by Springer Nature. This book was released on 2022-09-28 with total page 648 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook is a comprehensive volume on sprinklers and drip irrigation and covers all the basic and fundamentals concepts related to these topics. It is the first book to consider relative-flow-ratio as an evaluation criterion for both sprinkler and drip irrigation designs. It also discusses various types of sprinklers (used for irrigation), their complex layouts, design methodologies, selection criteria explained with practical examples, and their operations and maintenance under different conditions. In addition to operation and maintenance of drip irrigation components, the book also explains the drip irrigation hydraulics and various design aspects and the effect of the same on their performance. It also has one important chapter on Rhizosphere modelling which introduces the state-of-the-art technologies in optimal irrigation and fertigation scheduling. Worked out examples and solved problems in the chapters would aid to learning and understanding of the topic among the students. Given the contents, the book will be extremely useful for the undergraduate and postgraduate students of agriculture engineering, irrigation engineering and civil engineering. This textbook will also be useful for researchers, engineers and professionals working in these areas.
