Fluid Flow

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

Pascal's Law
Pressure applied to an enclosed fluid is transmitted undiminished to every portion of the fluid and the walls of the containing vessel.

Mercury barometer gauge: Consists of a long glass tube, closed at one end, that has been filled with mercury and then inverted in a dish of mercury [h of Hg in the glass tube is 760mm, P(Hg)=Patm]

Specific Gravity: p(Material)/p(Water) @ 4 degree Celcius [p(Water) @ 4 degree Celcius = 1000kg/m^3]
Archimedes's Principle
When a body is completely/partially immersed in a fluid, the fluid exerts an upward force on the body equal to the weight of the fluid displaced by the body [also known as buoyancy]

For any 2 points, assuming steady flow in an ideal fluid
