What is the requirement of CO2 in case of total flooding system?


Minimum requirement as per formula  :  Volume in  m3  x  mixing ratio ( % )
                                                                    Free CO2 volume  (0.56 m3 / kg)

  While calculating the ER space including casing, the mixing ration is taken as 35%
                                                     Excluding casing, the ratio is taken as     40%
                                                     For pump room the ration is taken as 40%

**If the relief valve outlet is taken to the open deck, then the free air volume of the air bottle need not be included.
