Consider a large uranium plate of thickness 10 cm and thermal conductivity k = 35 W/m-°C in
which heat is generated uniformly at a constant rate of é = 7 x 105 W/m³. One side of the plate
is insulated while the other side is subjected to convection to an environment at 40°C with a
heat transfer coefficient of h = 90 W/m²°C. Consider six equally spaced nodes with a nodal
spacing of 2 cm. The governing equation is
d²T é
