instructions:Q4: Characteristics of Flames & Fire Plumes (25 marks)4.1. Fire plumes are important in fire dynamics. Using a liquid fuel pool fire at the centre of a compartment as an example, explain the characteristics of a fire plume and generalise the axisymmetric plume model for calculating the smoke production rate and temperature along the axis of the fire plume. [15 marks]
4.2 Diffusion flames are common in compartment fires. Assuming a solid fuel is ignited, discuss and analyse factors that affect the spread of the flame on the solid fuel surface. If the fuel is a gas or a liquid, how the flame will spread? [10 marks]
