FIRE WATER DEMAND CALCULATION FOR HYDROCARBON STORAGE TANKS.

Fire water demand is calculated based on NFPA-11 and local regulation. for more details on step by step calculation read this article. 

Below calculator does not provide complete calculation but is made to facilitate the user in performing FW demand calculation.

Read the detailed Guide.

Fire Water and Water for Foam Generation

Reference Table NFPA 11

Foam Application Rates for Fixed Roof Tanks

Table A. Foam Application Rates for Fixed Roof Tanks.

Table 5.2.5.2.2 of NFPA 11

Table B: Supplemently Hose Selection Table

Table 5.9.2.2 from NFPA 11

Table C: Quantity of Fixed Foam Discharge Outlets

Table 5.2.5.2.1 from NFPA 11

ONLY FOR FIXED ROOF TANKS

Table D. Foam Application Rates for Open Top & Internal Floating Roof Tanks.

Table 5.3.5.3.1 of NFPA 11

Table E : Supplementally Hose Operating Time

Table 5.9.2.4 from NFPA 11

Table F: Foam Handlines and Monitors; Application Rates

Table 5.2.4.2.2 from NFPA 11

NOTE: Before using this table, refer to clause 5.2.4.1.1 and 5.2.4.1.2
