Problem Description:

A mild steel rod initially at $30C$ has both ends suddenly heated to $100C.$ The goal is to compute and plot the temperature distribution along the rod over time.

Given Data:

Length of the rod$(L)$:$30+13=43m$

Thermal conductivity $(k)$:$0\mathrm{.}2\frac{W}{m}-K$

Density $()$: $7000k\frac{g}{m^3}$

Specific heat capacity $(C_p)$:$510\frac{J}{k}g-K$

Thermal diffusivity $).$
