Where do calculations for a sprinkler system typically start?

Calculations for a sprinkler system typically start at the remote end head. This approach allows for an accurate assessment of system performance and ensures that each sprinkler head will receive adequate water pressure and flow rate. Starting the calculations at the remote end head acknowledges that various factors, such as friction loss in pipes and fittings, will reduce available pressure and flow as water travels from the source.

By conducting calculations from the furthest point (the remote end head) back to the water supply source, engineers can determine if the system will meet the required performance standards throughout its entire layout. This process helps identify potential issues early, allowing for adjustments to be made in pipe sizing, pump selection, or other components of the system, ultimately leading to more effective sprinkler system design and operation.
