Heat Transfer Flashcards
(5 cards)
1
Q
Fourier’s Law of 1D Conduction
A
Q̇cond = kA ΔT/Δx k = Thermal conductivity
2
Q
Newton’s Law of Cooling
A
Q̇conv = hA(Ts-T∞) h = Local heat transfer coeff.
3
Q
Stefan-Boltzmann Law
A
Q̇emit = σAT⁴ σ = Stefan-Boltzmann Constant = 5.67e-8
4
Q
Prandtl Number
A
Pr = Cpμ/κ
5
Q
Thermal resistance equation
A
Q̇ = ΔT/Rtot
Resistance formulas can be derived from the transfer methods’ matching laws.
