A metal bar has a cross section of A mm². The length of the bar is B m. The bar is heated from one of its ends using the heating rate of C W. Simultaneously, the other end of the bar is maintained at a constant temperature T = D °C. Determine the temperature distribution within the metal bar. The thermal conductivity of the metal bar is E [W/(m°C)]. Determine the temperature distribution using analytical calculations or computer software (Excel, Matlab). Draw a graph showing the temperature distribution as a function of distance x from the heated end of the bar According to the Fourier's Law the heat flux density [W/m²] as a function of distance equals q(x) = -k (x). Now the heat quantity Q [W] flowing through the bar becomes Q = qA = −kA¹ dT(x) dx dx Above, k is thermal conductivity [kW/(m°C)] A is the surface are of cross section [m²]
