Principles

Question 1

Pascals Principle

Answer 1

Any change in pressure applied to a completely enclosed fluid is transmitted undiminished to all parts of the fluid and enclosing walls

Question 2

Archimedes Principle

Answer 2

Any fluid applies a buoyant force to an object that is partially or completely immersed in it

The magnitude equals the weight of the fluid the object displaces

F(buoyant) = W(fluid)

Question 3

Equation of Continuity

Answer 3

The mass flow rate of a fluid is constant as long as no additional fluid is added or leaves the system
