It is observed that the temperature distribution, in steady-state, inside a one-dimensional wall with thermal conductivity equal to 50 W/mK and thickness of 50 mm has the form T(°C) = a + bx², where a = 200 °C and b = -2000 °C/m², and x is in meters. (a) What is the heat generation rate (q’’’) in the wall? (b) Determine the heat fluxes on both faces of the wall.
