Firefighting pump set serving multiple building

Question asked by amama01 on Feb 5, 2019

We have around 20 educational facility buildings require installation of firefighting pumps for sprinkler system and fire hose cabinets. It is planned to group 3 or 4 buildings with one fire pump set in a pump room located externally.     

When performing hydraulic calculation shall we make the calculation for the most remote area for one of the buildings and order the pump based on that (the result coming 500 GPM pump with 100 psi pressure), or should be additional flow rate added to the calculated result for the additional stand pipes in the other buildings.
