Radiative Heat Transfer Calculator Input Values |

Area of hot object (A_{H}) = m^{2} [square metre] |

Temperature of hot object (T_{H}) = K [Kelvin degree] |

Temperature of cold environment (T_{C}) = K [Kelvin degree] |

Stefan-Boltzmann constant (σ) = W/m^{2}K^{4} [Watts per square metre times Kelvin in power 4] |

Flowing time of heat energy through object (t) = s [second] |

Coefficient of emissivity (ε) = |

Please note that the formula for each calculation along with detailed calculations are available below. As you enter the specific factors of each radiative heat transfer calculation, the Radiative Heat Transfer Calculator will automatically calculate the results and update the Physics formula elements with each element of the radiative heat transfer calculation. You can then email or print this radiative heat transfer calculation as required for later use.
