Water Tank Volume & Pipe Size
Water Tank Volume & Pipe Size
(OP)
Hi, a water tank will be put in the third level floor or slab. What must be the volume if gravity tank will be used so the pressure would be strong at 2nd floor and ground? It will be primarily as wet fire system. The tank won't be used for any other water applications since the building already has water line. Any website to compute for it as well as pipe size to ensure strong pressure? Also are gravity or pressurized water tank recommended for such kind of application? Thank you.

That being said, I'm not so sure there is any requirement to furnish a tank in that situation. If you use a gravity tank, you'll have pretty minimal pressure available on the 3rd floor itself.
Where we more commonly see fire-protection tanks is where the local municipal supply is known to be limited, and there, they normally use gravity tanks plus diesel pumps.

The pipe sizing depends on the flow rates you need. It is common to see pipe sizes change along the length of the reticulation system according to the number and position of the nozzles.
Having said all that, I agree with JStephen that if you are asking this type of question you should not be taking the responsibility for the design of a fire system. Get a local contractor who knows the regulations.

You should be looking at a pressure tank or booster pump arrangement. The whole setup may be installed on the first floor.
