Fire & Life Safety Calculator
Screening-level fire protection takeoff: sprinkler heads, riser length, hydrant count, extinguisher count, alarm device count.
Heads = Area / Coverage · Riser = Floors × 3.2 · Hydrants = Perimeter / Spacing · Extinguishers = 2 × Floors · Alarms = 2 × Units Mechanical & Fluids Live Tool
Sprinkler Branch Hydraulic Calculator
Pressure balance along a sprinkler branch from Hazen-Williams friction loss, with the residual at the riser end and at the most remote head checked against the band you enter.
h_f = 10.67·L·Q^1.852/(C^1.852·d^4.87); Q = K·√P
