Derivative of newton's law of cooling
WebTherefore, in one dimensional, the following is the equation used: Q c o n d = k A T 1 − T 2 Δ x = − k A Δ T Δ x. When Δx → 0, the following is the equation in a reduced form to a differential form: Q c o n d = − k A Δ T Δ x. The three-dimensional form the Fourier’s law is given as: q → = − k T. http://mechatronics.engineering.nyu.edu/pdf/raise-newtons-law-of-cooling.pdf
