Question:
Consider a thin electrical heater attached to a plate and backed by insulation. Initially, the heater and plate are at the temperature of the ambient air, T∞. Suddenly, the power to the heater is activated, yielding a constant heat flux q: (W/m2) at the inner surface of the plate.
(a) Sketch and label, on T∞ coordinates, the temperature distributions: initial, steady-state and at two intermediate times.
(b) Sketch the heat flux at the outer surface q"x (L, t) as a function of time.
