Its query on selection of fire pump sizing as per NFPA20. Water demand is coming to 2300 usgpm. The selected fire pump is 2000 usgpm ?. As NFPA 20, cl no. 4.10 and A4.10 states fire pump capacity is selected within 90% to 140%. Here in this case 2300 usgpm is just 115% of the selected 2000 usgpm pump and will satisfy the maximum pressure

Hello,   I have the following question... According with NFPA 88A,2019 6.4.4 sprinklers shall not be required in open parking structures. Does this apply even if the building is mixed use: 37 total floors (commercial) and 5 floors exclusively for parking use? The consultant doesn't want to use sprinklers in those 5 floors.
