A moderate t2 fire breaks out in a 10 feet wide, 12 feet long, and 9 feet high room lined with ¾" gypsum wallboard. The 3 feet wide and 7 feet high door into the room is wide open. Determine the minimum heat release rate needed to cause flashover and the corresponding time after ignition to reach flashover using (a) Thomas Method, (b) Babrauskas Method, and (c) MQH Method. How do you explain the different heat release rates and times to flashover between the methods?
Your answer should show six calculations and your answers must include the proper units.
