Module 5: Hydraulic Systems Lecture 1 Introduction

2020-6-2  The hydraulic system works on the principle of Pascal’s law which says that the pressure in an enclosed fluid is uniform in all the directions. The Pascal’s law is illustrated in figure 5.1.1.The force given by fluid is given by the multiplication of pressure and area of cross section. As the pressure is same in all the direction,the smaller
