Gravity Flow Water Supply
Tackling a Gravity Flow Water Project for the first time? This book is intended to get you on your feet quickly. You'll learn how to select pipe sizes, work out the demand you need to meet, interpret topographic surveys and perform economic calculations to compare different alternatives. Besides producing a sound design, it will help you to get to grips with the materials, put in orders, supervise the building work, and most of what you will need in your quest for access to safe water.
Epanet and Development. How to Calculate Water Networks by Computer
This manual aims at walking the reader through the design of a water supply network in a Development context by explaining in a simple manner how to build and analyze a computer model of a water network with Epanet. Epanet is a free and widely used software from the U.S Environmental Protection Agency that models the hydraulic and water quality behavior of water distribution piping systems Arnalich Water and Habitat is an organization that helps improve the impact of humanitarian actors through training and consultancy in the fields of Water Supply and Environmental Engineering.
How to design a Gravity Flow Water System
This textbook teaches how to design drinking water systems and to do the calculations by hand. With minimal theory and through 28 progressive exercises, the most common scenarios are introduced one by one: branch lines, joining multiple sources, valley passes, pressure zones, and looped systems. Following simple, quick and reliable guidelines to achieve clear and tangible results for gravity flow water projects, the reader will learn how to decide on pipe diameters, check an existing design, and plan a system enlargement.
Epanet and Development. A progressive 44 exercise workbook
This collection of exercises has over 320 images designed to walk you step-by-step towards the modeling of water distribution systems which are commonly found in development work. You will learn how to load cartography and background images; to determine water demand and spatial allocation; to simulate the evolution of water quality in networks and to make economic comparisons, while avoiding the most common costly mistakes. This manual will help you make informed decisions for achieving clear and measurable results in development projects interventions. Epanet is a free and widely used software from the U.S Environmental Protection Agency that models the hydraulic and water quality behavior of water distribution piping systems.
Generators in development projects
Generators are an essential part of many projects and give rise to a very significant expenditure. This book introduces you to them from the management perspective. It is not about turning you into an electrician or a mechanic but about choosing the most suitable generator for your project and running it in the most economical way possible. You will learn how to improve existing installations, determine the power required, make informed choices between the different available options, oversee key aspects of the installation and avoid wasting energy that compromises the sustainability of the projects.
GPS & Google Earth for Development
This book shows you how to use a GPS and Google Earth to create simple and expressive maps to share on the web like the one shown on the cover. With a reading time of a mere 10 hours you will learn to work with a GPS without making mistakes, to use it with Google Earth including in areas without internet access and to quickly create diverse interactive maps that other people can see and modify over the internet without the need for experts or unnecessary complications. Even though it has been written in the context of Relief and Development work, the same process is valid for whatever other application.
Equipping a Borehole
This textbook teaches how to assess the viability of a borehole, select the required pump and generator, order materials with accuracy, and supervise the most important parts of the installation. The reader will be familiarized with the function and possibilities of the various components. Although boreholes can be equipped with a variety of pumps, only submersible electrical pumps are dealt with. The text deals with the stages from the time a drilling company bores a hole to a water aquifer to a fully operating borehole. All is explained in a simple, practical, and chronological manner.
Stand-Alone Solar Energy
What is a standalone photovoltaic system and how does it work? How many panels will I need to generate energy? What kind of batteries are going to work best? This self-contained book provides you with the tools to plan, size and install a standalone PV system, with numerous illustrations and worked examples to facilitate the learning process. You will be able to identify the components of an installation, select the most appropriate equipment, and design a low-power system, as well as learning about the installation, management and maintenance of off-grid systems to ensure they have a long working life.
Diesel Generator Auxiliary Systems and Instruments
This book is written for all people working in diesel generators business and specially for design and technical sales engineers who are welling to increase their knowledge in this subject. The book has nine chapters and covers all diesel generator auxiliary systems and instruments. It provides useful information, and is considered to be a good introductory book on diesel generator design. The book covers the diesel engine ratings and categorization, engine components, speed governing, electronic engine controls, fuel system, cooling system, coolant specs, lube oil system, oil specs, exhaust system, exhaust muffler and pipe sizing, electric starting system, battery and battery charger sizing, genset sensing instruments (switches, senders, RTD's, TC's, MPU's), genset indicating instruments. The book includes some tutorial questions at the end of each chapter.
A Handbook of Gravity-flow Water Systems for Small Communities
Originally written for the construction of gravity-flow drinking water systems in Nepal, this book is equally applicable for other locations around the world. Organized for quick reference, it is quickly and easily understood.
