This book is written for the average student who wants to learn the fundamentals of gas dynamics. It aims at the undergraduate level and thus requires a minimum of prerequisites. The writing style is informal and incorporates ideas in educational technology such as behavioral objectives, meaningful summaries, and check tests. Such features make this book well suited for self-study as well as for conventional course presentation. Sufficient material is included for a typical one-quarter or onesemester course, depending on the student’s background.

If you own, work with or are studying a water pump, sump pump, pool pump, chemical pump, industrial pump or any other type of pump, you will find the knowledge in this book by Mike Sondalini very valuable. Mike gives you insight to design, uses, installation, calibration, troubleshooting and maintenance for the various pump types in his book titled "Pump Types Explained". Mike starts out with details about the centrifugal pump with pump curves, cavitations and how to correct the situation. In addition to the centrifugal pump chapters, the peristaltic pump (hose pump), metering pump (dosing pump), gear pump, helical pump and the magnetic drive pump are explained. Of special interest during the design phase is Mike's cost / accuracy guide to pump types. Learn how to choose the right pump for the job, get a copy of "Pump Types Explained" now!

A hydraulic ram is a water-powered cyclic pump. It harnesses the forces of water hammer to pump a portion of the water being used to power the pump to a point higher than where the water originally started. It is sometimes used in remote areas, where the right conditions exist, since it requires no outside source of power other than the kinetic energy of falling water.

Chapters include: suction pumps and lift pumps, making simple suction pumps, pump cup leathers, pump valves, ram or plunger pumps, making a bucket and plunger pump, construction of a plumber's force pump, wooden pumps, small pumps for special purposes, centrifugal pumps, air-lift and pulsometer pumps, and hydraulic rams.

The book has been re-published from the original and contains the whole script, diagrams and formulas. The book has been reformatted and is not just a scanned copy of the original.

During the 1960's this book was pulled from all public libraries and banned for sale by the government. The reason was the experiments and information contained were considered too dangerous for the general public, especially young children. The hard copy of The Golden Book of Chemistry Experiments is extremely rare and very expensive if your lucky enough to find a copy for sale.

This educational and fun book shows you how to set up a home laboratory and how to conduct over 200 simple experiments. It is ideal for anyone who wants to learn more about this fascinating subject or for parents who want to broaden their child’s understanding of science.

This great book describes what chemistry is and covers the equipment required, the words used by chemists with meanings and allows you to conduct your own experiments and learn. Each experiment is set out in simple easy to follow steps and tells you what materials you will need and how to do it.

Slightly amended second edition. Nikola Tesla is famous for the Tesla Coil, but another of his inventions is the subject of this book and had nothing to do with electricity, other than as a possible means of generating it. This was his Disc Turbine for which a British Patent, which also covered a compressor variant, was granted in 1910. Unlike a conventional turbine, in which the rotor consists of bladed segments, in Tesla’s machine these were replaced by discs, working on the concept of flowing media being converted to rotary motion by friction working on the discs. Tesla claimed that a very small, but extremely powerful machine was possible using this principle - his aim was to produce a 25 hp machine that would fit inside a bowler hat. Here W. Cairns describes in detail the concept, and the history, of the original engines. He then proposes a number of uses for such turbines, including car and light aircraft use, all of which illustrate the extraordinary versatility of Tesla’s engine. Finally he provides the design and building instructions for a small Tesla turbine which any model engineer should be able to build. Not only does a Tesla Turbine provide a very high power to size ratio, it can be used as a compressor or pump. Tesla used steam on his test machines, and the model featured here would probably be run on compressed air, but the gas turbine principle can also be used; this really is a remarkably versatile machine. This versatility means that ninety four years after the original Patents were granted there are signs of re-awakened interest in Tesla’s machine, as many of the original problems can be overcome with modern materials. What is really exciting is that any revival can be boosted by individual experimenters- here is the place to start! High quality. 34 A4 format pages. Numerous drawings and sketches, including 6 pages of drawings specifically for a small Tesla turbine you can build.
