F_b = \rho g V

Buoyant force equals the weight of fluid displaced.

P = \frac{F_1}{A_1} = \frac{F_2}{A_2}

Pressure applied to a confined fluid transmits equally in all directions.

P + \tfrac{1}{2}\rho v^2 + \rho g h = \text{const}

Faster-moving fluid has lower pressure (energy conservation in flow).

F_b = \rho V g

Buoyant force equals the weight of displaced fluid.

\Delta P = \text{transmitted equally}

Pressure applied to a confined fluid transmits undiminished.

P + \frac{1}{2}\rho v^2 + \rho g h = \text{const}

Conservation of energy in fluid flow.

Re = \frac{\rho v L}{\mu}

Predicts laminar vs turbulent flow.

Q = Av

Volume of fluid passing per unit time.

A_1 v_1 = A_2 v_2

Conservation of mass in incompressible flow.
