Fluid Mechanics
Ideal fluid - fluid that is incompressible (density cannot change) and has no internal friction (viscosity)
-
Streamline - Curve whose tangent at any point is in the direction of the fluid velocity at that point

Pressure in a fluid at rest: The pressure difference between points 1 and 2 in a static fluid of uniform density is proportional to the difference between elevation y1 and y2.
This eqn shows when y increase, p decrease
If the pressure is at rest at the surface of incompressible liquid at rest is P0, then the pressure at depth h is greater by an amount ρhg.

Buoyancy
ARCHIMEDE'S PRINCIPLE: When a body is immersed in a fluid, the fluid exerts an upward buoyant force on the body equal to the weight of the fluid that body displaces.
-
Surface Tension: The surface of a liquid behaves like a membrane under tension. It arises because the molecules of the liquid exert attractive forces on each other.
-
-
Hydrostatics Equilibrium: Net force on the fluid is zero. It has equal pressure on opposite direction. Pressure difference gives rise to a net force.
