A. Required Parameters:
The design calculation is made in compliance with SOLAS Chapter II and NFPA 13, Installation of Sprinkler System
and Class rules and regulations.
1. Application rate required d = 5 /litres/min/m2 (minimum)
2. Pump capacity required Q = sufficient for simultaneous coverage of a
(minimum) minimum area of 280 m2
B. Sprinklers specification
Model 155F (68 deg C) 1/2" NPT CV PCH Qty = 226 pcs
Model 220F (93 deg C) 1/2" NPT CV PCH Qty = 9 pcs
(for galley, pantry and laundry)
K factor = 79 (Q in l/min, P in bar)
Minimum operating pressure = 0.5 bar
Minimum design operating pressure = 1 (according to NFPA 13)
Maximum operating pressure = 12 bar
Flow per sprinkler @ 0.65 bar = 79.00 l/min
Sprinkler spraying coverage = 5 m diameter at minimum 2.5 meter height
Maximum coverage = 19.6 m2 at 10 psi 66l/min
C. Calculations
1. Fire pump requirement (minimum)
For simultaneous coverage of a minimum area of 280 sq.m @ application rate of 5 l/min/sq m and 0.5 bar ar furthest nozzle.
Q = 280 sq m x 5 l/min
= 1400 l/min
= 84 m3/h
Actual capacity of fire pump = 1822.3 l/min (based on hydraulic calculation)
= 110 m3/h
2. Expected application rate calculations :
The protected area are enclosed by A or B class fire divisions as per Structural Fire Protection Plan.
Note:
Application rate above 5 l/min/m2 is acceptable.
