Consider a uniform bar of length L having an initial temperature distribution given by f(x), 0 < x < L. Assume that the temperature at the end x=0 is held at 0°C, while the end x=L is thermally insulated. Heat is lost from the lateral surface of the bar into a surrounding medium. The temperature u(x, t) satisfies the following partial differential equation and boundary conditions aluxx – Bu = Ut, 0<x<l, t> 0 u(0,t) = 0, uz (L, t)...
Partial Differential Equations Question: A homogeneous cylindrical rod of length L = 1 is insulated along the cylindrical side. At the end caps, heat exchange obeys Newton’s law of cooling, i.e. the flux is proportional to the difference of the temperature of the rod with that of the surrounding medium, written explicitly as ux(0,t) = u(0,t ) -T1 and ux(1,t) = T2- u(1,t) where T1 = 0 and T2 = 1. Find the steady state distribution of the temperature.

PDE. Please show all steps in detail. 2. Consider the 1D heat equation in a rod of length with diffusion constant Suppose the left endpoint is convecting (in obedience to Newton's Law of Cooling with proportionality constant K-1) with an outside medium which is 5000. while the right endpoint is insulated. The initial temperature distribution in the rod is given by f(a)- 2000 -0.65 300, 0<
