t squared fire ramp calculator

This calculator is designed to allow the user to determine how much energy a fire would produce at a given time (solving for heat release rate), based on the various growth factors and, conversely, an estimate of how long it would take a fire to reach a given heat release rate based on the various growth factors (solving for time).

This calculation is based on the estimate or assumption that growth is in proportion to time squared (t2).
