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<

Consider a 2 m long metal rod. The temperature u(z,t) at a point along the rod at any time t is found by solving the heat equation k where k is the material property. The left end of the rod ( 0) is maintained at 20°C and the right end is suddenly dipped into snow (0°C). The initial temperature distribution in the rod is given by u(x,0)- (i) Use the substitution u(z,t) ta,t)+20-10z to reduce the above problem to a...

2. In lectures we solved the heat PDE in 1 +1 dimensions with constant-temperature boundary conditions u(0,t)u(L,t) -0. If these boundary conditions change from zero temperature, we need to do a little bit more work. Consider the following initial/boundary-value problem (IBVP) 2 (PDE) (BCs) (IC) u(0,t) = a, u(x,00, u(L, t)=b, st. and let's take L = 1, a = 1, b = 2 throughout for simplicity. Solve this problem using the following tricks b and A"(x)-0 (a) Find a...
2. Consider the heat equation on a bounded domain with a zero heat-flux condition, 0<a <1 t > 0, u(z,0) = 2(1-2), (0, t) = 0, 14(1, t) = 0, t >0, t > 0, where σ > 0 is a constant. Such an equation is a model for the distribution of head throughout a rod which is thermally insulated on both ends. (a) Find the solution of the above PDE using separation of variables. You may use anything we...

Please show all steps in detail and as legible as possible. Thank you!!! Consider the two dimensional diffusion of heat in a rectangular section of tissue. Specifically solve for the temperature field, u(x,y,t), in the rectangular section with dimensions having (0<x < a) and (0<y < b), which is governed by the following initial-value, boundary-value problem, where a is a constant: (0,y,t) = 0 uy (x,0,t) = 0 14.

Problem 1. Find the general solution of an 1D heat equation: T(x, t) = 4Txx(x, t) with the boundary conditions T(0,t) = T(2,t) = 0. Note that T(x,t) denotes the temperature profile along x of a uniform rod of length 2. Problem 2. Solve the following 1D wave equation: 0ct(x, t) = 0xx(x, t) with the boundary conditions 0(0,t) = 0,(1,t) = 0, where 8(x, t) refers to the twist angle of a uniform rod of unit length. Problem 3....
Mark which statements below are true, using the following: Consider the diffusion problem au Ou u(0, t) = 0, u(L, t) = 50 u(x,0-fx where FER is a constant, forcing term. Any attempt to solve this using separation of variables fails. This is because the PDE is not homogeneous. A more fruitful approach arises from splitting the solution into the sum of two parts, taking into account that all change eventually dies out. That is there is a transient part...
