Calculation of Heat Transfer between Parallel Plates
Given parameters:
- Temperature of plate 1 (T1) = 1500 K
- Temperature of plate 2 (T2) = 500 K
- Emissivity of plate 1 (ε1) = 0.5
- Emissivity of plate 2 (ε2) = 0.25
We need to calculate the heat transfer between the plates.
Step 1: Calculation of Radiative Heat Transfer
The radiative heat transfer between the plates can be calculated using the Stefan-Boltzmann law:
q = σε1ε2(T1^4 - T2^4)
Where,
- q = Radiative heat transfer (W/m2)
- σ = Stefan-Boltzmann constant (5.67 x 10^-8 W/m2K^4)
Substituting the given values, we get:
q = 5.67 x 10^-8 x 0.5 x 0.25 x (1500^4 - 500^4)
q = 56.7 kW/m2
Step 2: Final Answer
The heat transfer between the plates is 56.7 kW/m2. Therefore, the correct answer is option A.
