SPRINKLER FLOW
K (K-factor)
Qspr = K · √P
P (Pressure, psi)
A (Area, ft²)
D (Density, gpm/ft²)
Sprinkler-Driven Flow
gpm
Qspr = K · √P
Density-Driven Flow
gpm
Qden = A · D
Governing Condition

Pressure vs. Flow

Note: This tool visualizes Sprinkler-Driven Flow (combination of K-factor and pressure) versus Density Driven Flow (Density × Coverage Area). The driver sets the minimum flow the sprinkler must achieve.
