Mean Free Path of Electrons Calculator
In thermodynamics, mean free path can be calculated in Copper from the atomic weight, valence electrons and density.
Note: Copper have one free electron per atom. Electron mean free path of (Copper) Cu to be 55 nm.

Formula:
U = VE * ro / Aw
Ep = 829.4 * U
C1 = 53.4 - 20.8 * U
C2 = 1.97 - 0.91 * U
γ = 0.191 / ro2
β = -0.10 + 0.944 / (√( Ep + BG2 )) + (0.069 * ro2 )
λe = 1000 / [ Ep (β × log(γ * 1000) - ( C2 / 1000 ) + (C1 / 10002)) ]
Where,
λe = Mean Free Path in Copper
Aw = Atomic Weight
VE = Valence Electrons
BG = Bandgap (Copper = 0.0)
ro = Density
U = Mean
Ep = Energy
C1, C2 = Radius
β, γ = Radio Active Charges
