Q4: A thick slab of copper initially at a uniform temperature of 20°C is suddenly exposed
to radiation at one surface such that the net heat flux is maintained at a constant value of
3×105 W/m². Using the explicit finite-difference techniques with a space increment of Ax
=
= 75 mm, determine the temperature at the irradiated surface and at an interior point that is
150 mm from the surface after 2 min have elapsed.

A) A flat wall is exposed to an environmental temperature of 38°C. The wall is covered
with a layer of insulation 2.5 cm thick whose thermal conductivity is 1.4 W/m. C,
and the temperature of the wall on the inside of the insulation is 315°C. The wall
loses heat to the environment by convection. Compute the value of the convection
heat-transfer coefficient that must be maintained on the outer surface of the
insulation to ensure that the outer-surface temperature does not exceed 41°C.
B) A vertical square plate, 30 cm on a side, is maintained at 50°C and exposed to room
air at 20°C. The surface emissivity is 0.8. Calculate the total heat lost by both sides
of the plate.
