I have a 6 storied garments building with 4 stairs. so i need 4 nos landing valves and 4 nos hose boxes for each floor. so how much GPM pump should i use. and what is the method. and what is the reference?  

 

some one told me that for the most remotest raiser need 500 GPM, and rest of 3 need 250 GPM each. so the calculation is 500+250+250+250= 1250 GPM pump. 

 

is this method is correct? if yes in NFPA where i can find it.
