Note: Default values are for heptane. Typical values: gasoline m_inf=0.055 kg/(m2s) k*beta=2.1/m; kerosene m_inf=0.039 k*beta=3.5; methanol m_inf=0.022 k*beta=large. Per Babrauskas (1983) and SFPE Handbook.

Babrauskas Pool Fire Model (SFPE Handbook Ch. 26): m''(dot) = m''(dot,inf) * (1 - e^(-k*beta*D)) m_dot_total = m''(dot) * A Q = m_dot * chi * delta_Hc Typical values: Gasoline m_inf=0.055 kg/(m²s), k*beta=2.1; Heptane m_inf=0.101, k*beta=1.1
