Based on Van Rossum (2027), §5.4, Walton and Thomas (2002), p. 3-184, and Tien et al. (2002), p. 1-85.<br /> <br /> Original vector illustration for [[Emissivity]], level 2 Intermediate.<br /> <br /> * Source basis: Van Rossum (2027), §5.4 (E = εσT⁴); Walton and Thomas (2002), p. 3-184 (873 K, ε = 0.5); Tien et al. (2002), p. 1-85 (ε = 0.33 for a 0.5 m wood smoke layer)<br /> * Alt text: Emitted heat flux against temperature for emissivities 0.33, 0.5 and 1; at 600 °C about 11, 16.5 and 33 kW/m².<br /> <br /> == Licensing ==<br /> New drawing by Fire Safety Academy. © Fire Safety Academy.</div>
