Hydraulics and Pneumatics

A technician's and engineer's guide

Hydraulics and Pneumatics: A Technician's and Engineer's Guide serves as a guide to the hydraulic and pneumatic systems operations. It features mathematical content that has been presented in a style understandable even to beginners and non-experts. It has nine chapters that cover both hydraulic and pneumatic machinery, their fundamental principles including safety standards and regulations. The book also features abundant referencing, updated web links, and masterful tables for easier understanding of the concepts covered. The text is written to serve as an introductory reference for novices and students in pneumatics and hydraulics. It is also invaluable and can be used as primary reference for control, manufacturing, mechanical, and electrical engineers, operations managers, and technicians working with hydraulic and pneumatic equipment.


Primary Audience: Control, fluid power, manufacturing, mechanical and electro-mechanical engineers, technicians and operations managers working with hydraulic and pneumatic systems and equipment.

Secondary Audience: Students enrolled at lower level college or trade school students taking classes in pneumatics and hydraulics.
