Question

The temperature of two large plates are maintained at 800 °C and 300 °C, determine: a) The net radiant heat exchange per square meter of the plates b) If a polished Aluminum shield (?= 0.5) is placed between the plates, find the reduction percentage in heat transfer The emissivity of the two plates (shown in Fig. 1) are 0.3 and 0.5 respectively.

Step 1

To work with the Stefan-Boltzmann law for radiation, we need to convert the temperatures from Celsius to Kelvin. The conversion formula is \(T(K) = T(°C) + 273.15\). - For the first plate at 800°C: \(T_1 = 800 + 273.15 = 1073.15 K\) - For the second plate at Show more…
