Pressure
$P = \frac{F}{A}$
Pressure at depth
$P = P_{0} + ρ g h$
Pascal's law
$\frac{F _{1}}{A _{1}} = \frac{F _{2}}{A _{2}}$
Density
$ρ = \frac{m}{V}$
Relative density
$RD = \frac{ρ}{ρ _{w a t er}}$
Archimedes' principle (buoyancy)
$F_{B} = ρ_{f l u i d} V_{s u b} g$
Law of floatation
$ρ_{b o d y} V g = ρ_{f l u i d} V_{s u b} g$
Equation of continuity
$A_{1} v_{1} = A_{2} v_{2}$
Bernoulli's equation
$P + \frac{1}{2} ρ v^{2} + ρ g h = constant$
Torricelli's theorem
$v = 2 g h$
Venturimeter flow
$v_{1} = A_{2} \frac{2 g h}{A _{1}^{2} - A _{2}^{2}}$
Viscous force (Newton)
$F = η A \frac{d v}{d x}$
Stokes' law
$F = 6 π η r v$
Terminal velocity
$v_{t} = \frac{2 r ^{2} ( ρ - σ ) g}{9 η}$
Reynolds number
$R e = \frac{ρ v D}{η}$
Poiseuille's law
$Q = \frac{π P r ^{4}}{8 η L}$
Surface tension
$T = \frac{F}{L}$
Excess pressure (drop)
$Δ P = \frac{2 T}{r}$
Excess pressure (bubble)
$Δ P = \frac{4 T}{r}$
Capillary rise
$h = \frac{2 T cos θ}{ρ g r}$
Surface energy
$E = T \times Δ A$
Pressure energy (Bernoulli term)
$\frac{P}{ρ}$
