Introduction to hydraulics
1.1
Objectives Upon completing this chapter, one should be able to: • Understand the background and history of the subject of hydraulics • Explain the primary hydraulic fluid functions and also learn about the basic hydraulic fluid properties • Understand how important fluid properties like velocity, acceleration, force and energy are related to each other, and also learn about their importance in relation to hydraulic fluids • Understand the concepts of viscosity and the viscosity index • Explain the lubrication properties of a hydraulic fluid.

Introduction and baclcground In the modem world of today, hydraulics plays a very important role in the day-to-day lives of people. Its importance can be gaged from the fact that it is considered to be one part of the muscle that moves the industry, the other being Pneumatics. The purpose of this book is to familiarize one with the underlying principles of hydraulics as well as make an effort at understanding the practical concepts governing the design and construction of various hydraulic systems and their applications. Additionally the functional aspects
