Question

Mechanical Engineering

In a slab of material 0.25 m thick and having a thermalconductivity 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 andx = 0.25 m and also the
temperatures and temperature gradients at these planes. If thedifference in heat flow at these
sections is due to the heat generation, determine the heatgeneration rate per unit volume.
