Consider a 20-cm X 20-cm X 20-cm cubical body at 477°C suspended in the air. Assuming the body closely approximates a blackbody,
Olin [163]

Answer:

a) The rate at which the cube emits radiation energy is 704.48 W

b) The spectral blackbody emissive power is 194.27 W/m²μm

Explanation:

Given data:

a = side of the cube = 0.2 m

T = temperature = 477°C

Wavelength = 4 µm

a) The surface area is:

A_{s} =6a^{2} =6(0.2)^{2} =0.24m^{2}

According Stefan-Boltzman law, the rate of emission is:

E=\sigma T^{4} A_{s} =5.67x10^{-8} *(477)^{4} *0.24=704.48W

b) Using Plank´s distribution law to get the spectral blackbody emissive power.

E=\frac{C_{1} }{\lambda ^{5}(exp(\frac{C_{2} }{\lambda T}) -1 )} =\frac{3.743x10^{8} }{4^{5}(exp(\frac{1.4387x10x^{4} }{4*477})-1)  } =194.27W/m^{2} \mu m
