WebMar 30, 2012 · In 1972, Heskestad proposed the following formula to calculate how fires grow: Q = .tn Q is the rate of heat release (kW) . is the fire intensity coefficient (kW/sn) t is time (sec) n is 1, 2, 3 For most flaming fires except flammable liquids and a few others, n = 2. When n = 2, this is called the T-squared growth rate. WebFeb 3, 2024 · Your mathematical equation is a model based on various assumptions about the world. If your model doesn't match the data (I am careful not to say "data does not match the model"), then your model is not correct, although it pretty darn good in some respects. Answers and comments here have provided improved models. $\endgroup$ –
