Answer :
The rate of radiation into surrounding space of the box shaped wooden stove at a temperature of 205 degrees Celsius is 8,453.82 J/s.
Rate of radiation of the wooden stove
The rate of radiation of the wooden stove is calculated as follows;
P = εAσT4
Where:
- ε is emissivity of the Surface
- A is surface Area
- σ is Stefan-Boltzmann Constant, 5.67 x 10⁻⁸ W/m²K⁴
- T is temperature in Kelvin, 205 ⁰C = 205 + 273 = 478 K
Surface area of the box
A = 2(Lw + Lh + Wh)
A = 2(0.75 x 1.2 + 0.75 x 0.4 + 1.2 x 0.4)
A = 3.36 m²
P = 0.85 x 3.36 x (5.67 x 10⁻⁸) x (478)⁴
P = 8,453.82 J/s
Thus, the rate of radiation into surrounding space of the box shaped wooden stove at a temperature of 205 degrees Celsius is 8,453.82 J/s.
