1

Fourier's Law of 1D Conduction

Q̇cond = kA ΔT/Δx
k = Thermal conductivity

2

Newton's Law of Cooling

Q̇conv = hA(Ts-T∞)
h = Local heat transfer coeff.

3

Stefan-Boltzmann Law

Q̇emit = σAT⁴
σ = Stefan-Boltzmann Constant = 5.67e-8

4

Prandtl Number

Pr = Cpμ/κ

5

Thermal resistance equation

Q̇ = ΔT/Rtot
Resistance formulas can be derived from the transfer methods' matching laws.
