Concentration Factors (W/V), English Units
a
The manufacturers listing specifies the temperature range for operation.
b
W/V [agent weight requirements (lb./ft.
3
)] = pounds of agent required per cubic foot of protected volume to produce
indicated concentration at temperature specified.
W = (V/s) X [c/(100-c)]
c
t [temperature (°F)] = the design temperature in the hazard area
d
s [specific volume (ft.
3
/lb.)] = specific volume of superheated FM-200 vapor can be approximated by the
formula:
s = 1.885 + 0.0046 t
where t = temperature (°F)
e
C [concentration (%)] = volumetric concentration of FM-200 in air at the temperature indicated.
