Spray Nozzle Data: misting
Spray nozzle performance data for fire protection, industrial cooling, gas scrubbing, dust suppression, and process applications. Covers full cone, hollow cone, flat fan, solid stream, misting, air atomizing, and NFPA 15 deluge nozzles. Key parameters: K-factor (Q=K*sqrt(P)), VMD/SMD droplet sizes, spray angle, flow rate, coverage area, material, and turndown ratio.
