Fluid mechanics and thermal physics

A = area

e = efficiency

F = force

h = depth

KEave = average molecular kinetic energy

l = length

M = molar mass

n = number of moles

N = number of molecules

P = pressure

Q = heat transferred to a system

T = temperature

U = internal energy

V = volume

v = velocity or speed

vrms = root-mean-square velocity

W = work done on a system

y = height

α = coefficient of linear expansion

μ = mass of molecule

ρ = density

$P=P_{0}+\rho gh$

$F_{b}uoy=\rho Vg$

$A_{1}v_{1}=A_{2}v_{2}$

$P+\rho gy+{\frac {1}{2}}\rho v^{2}$

$\Delta l=\alpha l_{0}\Delta T$

$P={\frac {F}{A}}$

$PV=nRT=Nk_{b}T$
