Fire Engineering Calculators
Flame Height and Temperature Calculator
This calculator can be used to determine the flame height and plume centreline temperatures based on correlations by Heskestad and McCaffrey.
t² (t-squared) Fire Calculator
This calculator can be used to determine the heat release rate of a t² (t-squared) fire at a certain time or determine the time it takes to reach a certain heat release rate.
Detector Activation Calculator
This calculator can be used to determine the activation time of a smoke detector or sprinkler using Alperts correlation.
Radiant Heat Flux (Simple)
This calculator can be used to determine the radiant heat flux recieved from an emitter at right angles.
Appliance Response Time Calculator
This calculator can be used to determine the response time of a New South Wales Fire Brigade appliance in accordance with the Fire Brigade Intervention Model.
Flame Size from an Opening Calculator
This calculator can be used to determine the flame size from an opening in an external wall of a building.
Fire Dynamic Simulator (FDS) Cell Size Calculator
This calculator can be used to determine what value (cell size) works well in accordance with the FDS User Guide
