It should be clear that ∫ 0 ∞ M λ d λ = ∫ 0 ∞ M ν d ν, and therefore I choose to integrate the easier of the functions, namely M ν. To integrate M λ, the first thing we would do anyway would be to make the substitution ν = c / λ. Planck's equation ...

網頁Nusselt number is equal to the dimensionless temperature gradient at the surface, and it provides a measure of the convection heat transfer occurring at the surface. The Nusselt number is named after a German engineer Wilhelm Nusselt. The conductive component is measured under the same conditions as the heat convection but with stagnant fluid. 網頁Modelling functional integration: a comparison of structural equation and dynamic causal models W.D.
