Hydraulic Flow Calculation (FPS Fire Fighting System) 1. Basic Concept Hydraulic calculation ensures that required flow and pressure reach the most remote sprinkler /hydrant point under worst-case conditions. It is based on: Flow demand (Q) Pressure requirement (P) Pipe losses (friction + fittings) Elevation differences 2. Core Hydraulic Formula Flow-Pressure Relationship (Sprinkler) Q=KPQ = K \sqrt{P}Q=KP Where: Q = Flow rate (LPM or GPM) K = Sprinkler discharge coefficient P = Pressure at sprinkler (bar or psi) 3. Head Loss Calculation (Pipe Friction) Hazen-Williams Formula (most commonly used) As forluma given in image. 4. Total Head Requirement Total Pump Head HT=Hs+Hf+Hv+Hr Where: Hs = Static head (height difference) Hf = Friction loss Hv = Velocity head Hr = Residual pressure required at sprinkler/hydrant 5. Typical Data Center Design Criteria For data centers (high-value assets): 5 reaction
