Summary

Effective heat transfer coefficient of 16 mm gypsum plaster against time; the thermal penetration time is about 161 s. Based on Walton and Thomas (2002), pp. 3-176–3-177.

Original illustration for MQH correlation, level 4 Expert.

Source basis: Walton and Thomas (2002), p. 3-176 (Equations 13 to 15) and p. 3-177 (example values: tp = 161.3 s, hk = 0.24, 0.098 and 0.03)
Alt text: Line chart: heat transfer coefficient of a gypsum plaster lining falls with time, then drops to a constant value at 161 seconds.
