You are providing confusing information. Normally you would not include the sprinkler demand with the deluge demand. It looks like you have two demand conditions - deluge + hose = 1800 gpm and sprinkler + hose = 1000 gpm. Why do you use 2500 gpm for your demand?

What I want to ask is simulating a real project like below: Imagine in a factory I want to select fire pump for my below demand: 1- Total demand of deluge system: 1500 GPM 2- Total demand of wet pipe sprinkler system: 700 GPM 3- Total demand of hose streams: 300 GPM. Total water demand: 2500 Gpm, Total pressure: 100 psi For this project as my source of power is reliable, I want select TWO parallel electric pumps with below specifications: Scenario 1: Two pumps( First: 1250Gpm ,100 Psi - Second: 1250 Gpm ,100Psi ) Scenario 2: Two pumps( First: 1500Gpm ,100 Psi - Second: 1000Gpm ,100Psi ) Scenario 3: Two pumps( First: 1500Gpm ,100 Psi - Second: 1500Gpm ,100Psi ) As my deluge demand is 1500 GPM, so which scenario is the best for my project? Note that I want to select one of the above scenarios and don't have any other options. Would you also please analyze each item. Thanks, Reza --------------------------------- Be a better Heartthrob.
