The amount of FM-200 clean agent required to achieve the design concentration shall be calculated based on NFPA 2001, table A-3-5.1 as follows:

W = ( V/S ) x ( C/ ( 100-C ) )where:W=FM-200 weight, kgV=net volume of the hazard, m3S=specific volume of superheated FM-200 at atmospheric pressure and temperatureS=0.1373m3/kgC=FM-200 design volumetric concentration, 7% by volume
