The temperature of an exotic liquid in a pipe of length L = 2 can be described by the 1D non-dimensional heat equation ƏT (1) Ət with time t, temperature T, temperature dependent thermal diffusivity a(T), and a source term describing additional heating/cooling along the pipe, Q(x, t). On the left end of the pipe, the fluid has a temperature of sin(t). On the right end, the boundary is adiabatic At t=0 the temperature of the fluid is = = a (T): a(T) = T(x = 0, t) = 2 ƏT 0²T əx² ?x The thermal diffusivity of the fluid can be modeled as + Q(x, t) - (x = L, t) = 2 10 = 0. T(x, t0) = 2. = ao+a₁T+ a₂T² + a3T³. For a grid of M+ 1 equally spaced points along the pipe and h the spacing between points: Tasks: ล (3) (4) (5) a) write the equation for the temperature at the first point Tr using Eq.
