Evaporative Heat Transfer Calculator Input Values |

Area of human body (A) m^{2} [square metre] |

Coefficient of heat transfer through evaporation (h) W/Pa∙m^{2} [Watts per Pascal times square metre] |

Evaporation time (t) s [second] |

Pressure of water vapour near the skin (p_{s}) Pa [Pascal] |

Pressure of water vapour in the environment air (p_{0}) Pa [Pascal] |

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