Figure 42  Isometric 07 – Fire Protection Sprinklers

The sprinkler system protects three areas of the building. The production area has 16 sprinklers, spaced at 15 foot intervals. Each sprinkler head must provide a flow rate of 15 gpm US (57 l/min) when all sprinklers are operating.


The office and storage area is protected by 20 sprinklers heads spaced at 10 foot intervals. Each sprinkler head must provide a flow rate of 9 gpm US (34 l/min) when all sprinklers are operating.


The sprinkler heads have been modelled by creating a 'spray' component to specify the flow rate and head loss characteristics of the spray nozzles. The 'spray' component has been added to the pipes with an 'end pressure' of 0.000 psig, i.e. where the pipe discharges to atmospheric pressure.
