Summary

The fitted milk-powder example predicts a smaller critical layer thickness at the higher ambient temperature. Based on Gray (2002), chapter 2-10, p. 2-226.

Original illustration for Self-heating, level 3 Advanced.

Source basis: Gray (2002), chapter 2-10, p. 2-226, milk-powder example; calculations/self-heating.py.
Alt text: Calculated critical layer thickness is about 0.374 m at 80 °C and 0.0166 m at 200 °C for the source example.
Accuracy notes: Not allowable operational thicknesses. Keep r distinct from2r and identify the assumed two-face slab exposure.
