water tanks-net capacity
water tanks-net capacity
(OP)
I am sorry for this rookie question, but I can not find where the norm NFPA stablishes how to calculate the volume that the water tank for private fire protection should have.
I only found the "standard net capacity sizes" on the NFPA22, but I didn´t find any tips on how to determine the size.
Can anyone please help me to find it?

RE: water tanks-net capacity
Sprinkler demand + inside hose streams + outside hydrants times the duration based on the occupancy. Light 30 min, Ordinary Haz 1 & 2 60 mins, Extra Haz 1 & 2 120 mins. Warehouses 120 mins, ESFR 60 mins.
Example
Light hazard .10/1500= 150 gpm plus 100 gpm hose = 250 gpm times 30 mins = 7,500 gallons. If no inside hose then deduct 100 gpm.
Hope this helps.
