The attached fire fighting design excel sheet contain following;
Steps involve in design calculations
- Determine the system type and configuration
- Determine the hazard class of occupancy
- Determine the area protected by each sprinkler
- Determine the type of sprinkler used in each area, get K factor
- Determine pipe sizing method
- Pipe schedule method
- Hydraulic calculation
- Determine the area of sprinkler operation (ft2)
- Select a hydraulic design density (gpm/ft2)
- Calculate minimum flow and pressure at the hydraulically most demanding sprinkler
and sheets for doing all above steps.

The fire fighting design calculation sheet is attached below.
