This is a government report showing the results of mechanical tests performed on pumping plants in Southern California used to raise water for irrigation. Three types of plants were tested, namely, plants driven by gasoline engines, plants driven by electric motors, and steam-driven plants. The tests were planned and carried out by J. N. Le Conte and C. F. Tait. S. M. Woodward contributed much of the analysis and discussion and checked all of the tables in the report. The report was completed under the direction of Elwood Mead, Chief of Irrigation and Drainage Investigations. The tests and report were jointly overseen by the Irrigation and Drainage Investigations of the Office of Experiment Stations and the State of California.

Paperback. Condizione: New. Print on Demand. This book compiles the findings of a study conducted in early twentieth-century California to ascertain the mechanical efficiency and running costs of various water-pumping systems in use at the time. The study's primary focus is on gasoline, electric, and steam-powered pumps, and their respective fuel consumption, power usage, and water-lifting capacity were measured across dozens of pumping plants. The author takes care to describe the equipment setup and methodology of each test in detail, allowing readers to verify the results or replicate the study for their own purposes. In presenting this valuable historical data, the author contributes to our understanding of the evolution of water-pumping technology and provides a glimpse into the energy landscape of early 20th-century California, where innovative solutions were sought to meet the challenges of water scarcity and distribution. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
