Archimedes Principle/Law
- Archimedes' principle states that the upward force which is exerted by an object that is either partially or fully immersed in a fluid is equal to the weight of the liquid displaced by the object. This principle helps to prove the Law of floatation.
- The law of floatation states that the weight of a floating body is equal to the weight of the liquid displaced by it.
- For Example- A ship or submarine in the ocean does not sink until the weight of the water it displaces is equal to its own weight
Principle of floatation
When a body displaces a weight of water equal to its own weight, it floats. This is known as the principle of floatation.
FB = weight of fluid displaced = weight of the body
Additional Information
Pascal’s Law
In a static fluid pressure at a point is equal in all directions.
Conversely, if pressure is applied to a static fluid, it will be transmitted equally in all directions.
Example: hydraulic lift, hydraulic press and hydraulic brakes.
It can also be applied to flowing fluid if the fluid is ideal.
Bernoulli’s theorem
According to Bernoulli's theorem, in a steady, incompressible, and irrotational flow the sum of pressure energy, kinetic energy, and potential energy per unit mass is always constant.
Darcy's Law
The Darcy - Weisbach equation is one of the most commonly used equations for estimating frictional pressure drops in internal flows.
Where D is the hydraulic diameter.
D = 4A/P = 4m (A = area, P = wetted perimeter)
