Hydrostatics

35.1.INTRODUCTION

The term ‘hydrostatics’ means the study of

pressure exerted by liquids (such as water, oil etc.) at

rest, on the container or any other surface immersed

into it. In this chapter, we shall discuss total pressure

and its position (i.e. the point, where total pressure acts)

on a surface.

It has been observed that the direction of such a

pressure is always at right angles to the surface, on

which it acts. In this chapter, only the study of water

will be dealt with, unless specified, otherwise.

35.2.INTENSITY OF PRESSURE

The force exerted by a liquid per unit area on a

surface is called intensity of pressure which is generally

termed as pressure.
