The complete combustion of any material dictates the maximum latent heat output during a fire. However, real materials undergo incomplete combustion, and thus some percentage of AH. A lkg sample of a polystyrene (PS) plastic part is burning in a 5mx8mx2m closed bedroom. If the complete combustion reaction of PS is given as: PS(s)+900000,(g) → 72000C02(g) +36000H,0(1) Calculate AH, and the real heat output of the fire if the incomplete combustion is only 15% of the complete combustion (AH, of PS is -76.87x10 and has a MW of 900,000). If air has a Cm of 29.19 r a density of 1.225 kg/m, mol mol mol K and assuming that all of the heat is trapped in the room, what is the room temperature if the initial room temperature (T.) was 25 °C? If the volatile organic compounds (VOCS) emitted during the burning has a flash point of 65 °C, will flashover oceur when a firefighter smashes the door down and oxygen floods into the room (is T2 the flash point)?
