Can anyone have an idea about , how to calculate pressure & design density requirement as per NFPA 13 ?
Why the question?
There are computer programs that do fire sprinkler hydraulic calculations
Base on occupancy , how we can select design density from graph ? Hydraulic calculation is later stage.
Based on occupancy, you need to find hazard classification. That will gives the design area. After that you can find the design density from graph.
Why the question??
Do you work for a fire sprinkler company ?? Or other??
I am not a designer or engineer
Sometimes there are a lot of variables.
I am not near the book, but my first response would determine what hazard you are designing to light, ordinary, etc
Suggest you post the question here also:::
