Question:
The spectral emissivity of unoxidized titanium at room temperature is well described by the expression ελ. = 0.52λ–0.5 for 0.3μm < λ < 30μm.
(a) Determine the emissive power associated with an unoxidized titanium surface at T = 300 K. Assume the spectral emissivity is ελ. = 0.1 for λ > 30μm.
(b) Determine the value of Amax for the emissive power of the surface in part (a).
