Thank you really helpful and easy to understand

[@irfancfps]

Most welcome

[@mdshadab_Fire_Safety_knowledge]

Nice and informative👍

[@irfancfps]

Thank you.

Sir, In case the suction is at the bottom of the tank, then it would be required to give the clearance at the bottom or not?

[@irfancfps]

Practically it will not be possible

[@imranhadi8505]

Please explain that how can we know that how much capacity of fire water tank is required for a specific area.

[@irfancfps]

It depends on the fire pump selected and storage capacity duration. These two can be calculated based on the fire flow requirements per local building codes. However, NFPA 13 has water supply duration requirements for light, ordinary, extra hazard occupancies. we can consider those as well in case you do not have any local building codes.

Asalamualaikum Mr.Irfan, on top of tank there is Vent ( AAV), how to calculated size and Other Question at Highest pipe/ top there is AAV (automatic air Vent) Hydrant box pipe, how calculate size dia. Thank you very much.

[@irfancfps]

Walekumassalam. Mostly AAV outlet size will be minimum 1/2'' in size. I could not find much data on sizing of air vents in nfpa. However, this is not a matter of concern because, they are used only to release the accumulated air in pressurized clean and wastewater systems. They protect systems from damage due to air-related surges and improve system efficiency.
