Presentation on•Importance of fluid mechanics in our daily life.

by Mehedi Hassan Sourav

3

Fluid• Fluid mechanics is the branch of science that studies the

mechanics of fluids (liquids, gases, and plasmas) and the forces on them.

4

Fields of Fluid Mechanics

5

History• Archimedes• Buoyancy• Leonardo di Vinci• Isaac Newton• Abu Rayhan Biruni• Al Khazini• Blaise Pascal• Bernoulli.

6

Importance of Fluid Mechanics

• The importance of fluid mechanics can not be described within some topics as it has a wide range of uses.

7

The most talked things………….

•Air Condition

8

• Gas Turbine

•Rocket Engine

9

•Aerodynamics

10

•Refrigeration system

• Submarine

11

• Supersonic Aircraft

•Bike

12

They are………………….

• Those are the large structure of performing work done for the help of using Fluid Mechanics . But small many things that usually we are not think so far about the uses of fluids in our daily life…….

13

• Rain Droplet

• What makes the rain form little droplets? Could it be surface tension...

14

•Hot Air Balloons

• a hot air balloon rises because the air inside the balloon is hotter than the air outside the balloon. the forces acting on the balloon, we realize a buoyancy force is pushing upwards on the balloon.

15

• Tree..!!!

• the drag force on a single leaf would be different than the drag force on an entire tree. this makes sense when we think about it because force is pressure times area. If we increase the area, we will increase the force.

16

• Shower • Soap Denser

17

•Blood Circulating.• The flow of blood through your veins is much like

that of a fluid flowing through a pipe. The flow of blood is steady and laminar

18

•Water pipe •Honey

19

• Fluid mechanics while travelling

20

• Hair Dryer

• Many girls we know blow dry their hair on a regular basis. Like them, we enjoy this commodity of everyday life. if we center the blow dryer above our head and point down, we can feel the shear force of the air blowing over our face and hair.

21

• Actually,I said before the branch of fluid mechanics are huge as it has a large field in different sector.Though it causes a little bit demerits,after all it’s importance is huge in our everyday life also the engineering sector.So,For being a good Engineer it have to be go through.
