Whats is the NFPA definition of "Hose Allowance"
For Sprinkler System i.e foam system do we consider "Hose allowance" while sizing the fire pump?
My understanding was "Hose allowance" was added to the sprinkler demand to size the firewater storage.
The "hose allowance" is the additional water demand that is added to the system when fire hose connections are present. It must always be considered to size up both the fire pump and the fire water storage, unless the sprinkler/foam system does not have fire hose connections.
