Thrust And Pressure
Chapter Name : Gravitation |
Sub Topic Code : 101_09_10_05_02 |
Topic Name : Thrust And Pressure |

Sub Topic Name : Pressure In Fluids |

Introduction
Any fluid, including water exert force on the bottom of the container (bottom layers) by the virtue of its mass. Thus, as the depth increases in the sea, the pressure increases too.
Pre-Requisites:
Gravity, Pressure, Mass
Activity:
If you are a really good swimmer, observe the difference in the pressure you experience at the surface of water and when you are at a considerable depth.
Real Life Question:
Deep sea divers often die because they ignore the effects of force exerted by the water at depth. Hence there are special suits to protect them. How does water exert a force on these divers?

What you learn in Theory:
The concept of pressure and thrust in context of fluids.
What you learn in Practice:
How the analysis of this pressure and thrust exerted by the fluid particles is necessary in the design of large machines like Aircrafts and ships.
