Plot the heat release rate of a fire that has the following characteristics:
Initial growth as a t2 fire at a rate that achieves a convective heat output of 1.5 MW after 150 seconds until sprinkler activation.
Sprinklers activate when the total heat release rate of the fire has grown to 3 MW.
The sprinkler system has been designed to an “Ordinary Hazard” occupancy with a discharge density of 0.08 mm/s. Following sprinkler activation the heat release rate of the fire follows the “NIST” equation fore sprinkler suppression.
