了解如何使用Radiant Heat Exchange Parallel Flat Black Plates of Equal Size计算器及其工作原理

This calculator is used to determine the heat transfer between two parallel flat black plates of equal size. The heat transfer is calculated using the Stefan-Boltzmann law, which states that the total energy radiated per unit surface area of a black body across all wavelengths per unit time (T⁴) is directly proportional to the fourth power of the black body's absolute temperature.

How to Use:

  1. Enter the temperature of the first plate (T1) in degrees Celsius.
  2. Enter the temperature of the second plate (T2) in degrees Celsius.
  3. Enter the emissivity (ε) of the plates. A black body has an emissivity of 1.
  4. Click the "Calculate" button to compute the heat transfer rate.
  5. The result will be displayed in watts per square meter (W/m²).

The formula used is Q = ε * σ * (T1⁴ - T2⁴), where Q is the heat transfer rate, ε is the emissivity, σ is the Stefan-Boltzmann constant, and T1 and T2 are the temperatures of the plates in Kelvin.
