Fire sprinkler system design concept

[Hasni2]

Just want to know a little idea as to how many sprinkler heads can one i connect with a 4" dia line, 3" dia line, 2" dia line and so on. Would be great if someone could share it in a tabulated form, like making a table and putting different dia lines and sprinkler heads against each. I am after a small warehouse firefighting designing and intend to install a fire sprinkler system there. Thanks

Is this in the US???

Most systems are hydraulically designed

 

[LCREP]

The following is from NFPA 13 for an extra hazard pipe schedule system. The maximum head spacing is 100 ft.².
Pipe size: number of heads
1" :1
1.25:2
1.50:5
2:8
2.50:15
3:27
3.50:40
4:55
5: 90
6:150

BUT as CD said the system should be hydraulically calculated
