Fourier Number Calculator

Calculate the Fourier number using the formula:
\[ Fo = \frac{\alpha\, t}{L^2} \]

* Enter thermal diffusivity \( \alpha \) (m²/s), time \( t \) (s), and characteristic length \( L \) (m).

Step 1: Enter Parameters

Thermal Diffusivity, \( \alpha \) (m²/s):

Example: 1.2e-5 m²/s

Time, \( t \) (s):

Example: 3600 s (1 hour)

Characteristic Length, \( L \) (m):

Example: 0.05 m
