Reference Answer

(a)
(b) The automatic water sprinkler system is an automatic fire detection, alarm, and extinguishing system that can quickly and effectively deal with any outbreak of fire that may occur in accommodations or other spaces on ships.
A tank (half filled with fresh water) initially charges the entire system with fresh water at a pressure of about 8 bar and maintains it under pressure with compressed air.
It is also connected to an independent seawater pump with its own seawater suction. Each sprinkler head has a quartzoid bulb, which retains a diaphragm seal in the outlet of the water pipe.
