a
The manufacturer’s listing specifies the temperature range for operation.
b
W/V [agent weight requirements (kg/m
3
)] = pounds of agent required per m
3
of protected volume needed
to produce the indicated concentration at the temperature specified.
c
t [temperature (
o
C)] = the design temperature in the hazard area.
d
s [specific volume (m
3
/kg)] = specific volume of superheated HFC-227ea vapor can be approximated by
the formula: s = 0.1269 + 0.0005(t)
e
C [concentration (%)] = volumetric concentration of HFC-227ea in air at the temperature indicated.
