h is hamiltonian, considering ideal gas.
h = p^2/2m.
therefore, J = sum (v * p^2/2m) = k * v^3
J the thermal current. v is velocity. k is some constant. | F****y

Nu=kRe^nPr^m
Re: Reynold number
Pr: Prandtle number
m: ~0.3
n: ~? sorry, I forget, but you can find this equation at any level heat

: J = sum ( v * h)
: h is hamiltonian, considering ideal gas.
: h = p^2/2m.
: therefore, J = sum (v * p^2/2m) = k * v^3
