In a slab of material 0.25 m thick and having a thermal conductivity of 45 W/mK, the
temperature °C at x under steady state is given by T = 100 + 200x – 400x2 when x is measured
from one face in m. Determine the heat flow at x = 0, x = 0.125 and x = 0.25 m and also the
temperatures and temperature gradients at these planes. If the difference in heat flow at these
sections is due to the heat generation, determine the heat generation rate per unit volume.
