Calculate the occupant moving speed given occupant density

Calculate the occupant moving speed; given occupant density = 0.15 persons/feet^2 and k = 275.

Solution

occupant moving speed = k - a* k* D

where- D- occupant density = 0.15 (given)

k - constant = 275 (given)

a- constant = 2.86 ft/min

Therefore occupant moving speed = 275 - 2.86*275*0.15 = 157.025 ft/min
