For a retrofit project with a 40 years old sprinkler system. Would it be acceptable to have branch lines and main pipes at a water velocity of about 110 ft/s. A high rated fire pump would be added, but this would avoid replacing the small diameter piping in the existing tenant spaces. Is there risk of breaking the pipes at this velocity, or blocking the sprinkler system with debris dislodging from the existing pipes?
Hydraulic calculations would not be accurate at this velocity but maybe a safety factor on the sprinkler demand could be added for this?
