Overview

Fluid pressure is the pressure exerted by a fluid at rest on the walls of a container or on any surface in contact with it. A fluid has no definite shape of its own and can flow, so it includes both liquids and gases. Pressure in fluids becomes important in many situations such as deep water, blood

Key Concepts

A fluid is a substance

A fluid is a substance with no definite shape of its own. It assumes the shape of its container and can flow. Liquids and gases are fluids.

Fluid thrust is the total normal

Fluid thrust is the total normal force exerted by a fluid at rest on a surface in contact with it. The force is always perpendicular to the surface be

Fluid pressure is the thrust exerted

Fluid pressure is the thrust exerted by a fluid at rest per unit area of the surface in contact with it. The relation is p = F/A.

The SI unit of pressure

The SI unit of pressure is newton per metre squared (N m^-2) or pascal (Pa). Its dimensional formula is [M L^-1 T^-2]. Pressure is a scalar quantity.

The pressure difference between two points

The pressure difference between two points in a liquid separated vertically by height h is p = p2 - p1 = hρg. Therefore, pressure at a depth depends o

Learning Objectives

  • Understand the meaning of fluid, fluid thrust, and fluid pressure
  • Use the formula p = F/A to relate force and pressure
  • Study how pressure changes with depth in a liquid column
  • Apply Pascal's law to hydraulic lift and hydraulic brakes
  • Explain why pressure depends on depth and not on container shape
