3 Design of Deluge System and Calculation
For hazardous chemical processing building of class 1.3 explosives, designing a
deluge valve (as shown in Fig. 2) requires parameters as per TAC norms. Those
parameters are
• Design density: 10.2 LPM/m
2
• Minimum pressure at remotest nozzle, P = 1.4 kg/cm
2
= 1.37 × 10
5 pa
• Velocity in feed lines: 5 m/s
• Space between nozzles: 2–3 m
• Each nozzle covers an area: 6 m
