Derive newton's law of cooling

WebNov 8, 2010 · The second part of the paper is an attempt to reconstruct Newton's transient cooling experiment using modern knowledge of heat transfer. It is necessary to allow for varying heat transfer coefficients and specific heats and hence a numerical approach has to be used on a computer. WebNewton’s law of cooling and Ohm’s law are a discrete and electrical analog of Fourier’s law. Differential Form Of Fourier’s Law Fourier’s law differential form is as follows: q = − k T Where, q is the local heat flux density in W.m 2 k is the conductivity of the material in W.m -1 .K -1 T is the temperature gradient in K.m -1
