Abstract:

Systems and methods for determining, characterizing and/or predicting the impact of a sprinkler discharge spray on a fire induced mass flow through a vent, preferably a doorway, of a compartment. Provided are systems and methods for determining a sprinkler coefficient that characterizes the ability of a sprinkler to reduce a fire induced mass flow from the compartment. The sprinkler coefficient preferably defines a ratio of a mass flow from a compartment, in the absence of a discharging sprinkler, to the mass flow from a compartment, in the presence of a discharging sprinkler. Accordingly, the systems and methods herein provide for the sprinkler coefficient to define a mass flow equation by accounting for the influence of a discharging sprinkler spray and provide for a new fire induced mass flow calculator.
