a)Explain the relationship between walking speed, occupant density and flow rate. Define effective width in the evacuation analysis. Explain how to use effective width in the evacuation analysis.
b)Define pre-movement time.Explain the reason why pre-movement is hard to quantify. Explain how to determine pre-movement time in the fire safety design of a 4-storey residential building
.c)Take the following meeting roomshown in Figure Q1as an example. Explain how to estimate the the evacuation timeand list the key procedures(i.e. travel and queuing time) of this meeting room.Assume the total occupant load is X
