We have scenario where we are using foam system under NFPA 11 for a floating roof tank with Crude Oil.
Based on our previous calculation for a prior tank the fire water demand is 1,926 gpm so we have existing 2,000 gpm pump to be able to supply the required flow. But an additional Crude Oil tank has been added and we have run our new hydraulic calculations and we come up with 4,496 gpm new flow requirement.
Is there a way we can still use the existing fire pump?
