a
W / V [agent weight requirements (lb/ft
3
)] - pounds of agent required per cubic foot of protected volume to
produce indicated concentration at temperature specied.
b
t [temperature (°F)] - the design temperature in the hazard area.
c
s [specic volume (ft
3
/lb)] - specic volume of FM-200® vapor may be approximated by the formula:
s = 1.885 + 0.0046t
where t = temperature (°F)
d
C [concentration (%)] - volumetric concentration of FM-200® in air at the temperature indicated.
