PASCAL’S PRINCIPLE

ARCHIMEDES’S PRINCIPLE

BERNOULLI’S PRINCIPLE

The principle of transmission of liquids states that pressure is transmitted equally in all directions

Upthrust acting on an object is equal to the weight of the fluid that the object displaces.

When a fluid (liquids or gases) moves with a high velocity, its pressure is reduced or vice versa

(daya tujah yang bertindak ke atas suatuobjek sama dengan berat cecair yang disesarkan))

(apabila bendalir (cecair atau gas) bergerak dengan halaju tinggi, tekanannya dikurangkan dan begitu juga sebaliknya))

Design of vehicles in water (ships and submarines)

FORMULA / CONCLUSIONS

P = F/A

DIAGRAMS

Upthrust acting on object = weight of water displaced

-

high velocity, low pressure low velocity, high pressure
