HRR for heat detector response

sfpe_handbook_chapter_14_heat_release_from_temp_and_position

Calculates the heat release at which a heat detector submerded in the ceiling jet will activate

Equations

\dot{Q} = \left((T-T_\infty) \cdot \dfrac{H^{\frac{5}{3}}}{16.9}\right)^{\frac{3}{2}} or \dot{Q} = \left(\dfrac{(T-T_\infty) \cdot \left(\dfrac{r}{H}\right)^{\frac{2}{3}} \cdot H^{\frac{5}{3}}}{5.38}\right)^{\frac{3}{2}}
