Hi There, I hope All is good With u.
First of all, i am thankful for ur Helps
Question:
As Recomended in NFPA we should Discharge CO2 in 1 Min For Surf Fire and 7 Min For Deepseat,
Now in NFPA 5.5.2.2 All Calculation refer to 6.3.2.3 ( A new Formula) also there are two another method ! Rate By Area and Rate by Volume ! I comfused !!!!!!
How i sall Calculating Discharge flow rate for CO2 Suppression System ?
on the Other hand When i want Calculating Flow rate For DeepSeat, Should I divid Total CO2 Amount to 7 min or i Should Consider and calculating according 30% Concentration.
I add Fike Company Sample, Please see Page 6 and 12 Solved Method . it is really weird.
