How do you calculate fire protection?
7 Steps to Complete a Fire Suppression System Estimate
- Consider the Project. The first thing to consider is the project itself.
- Check the Specs. The next thing to check is whether the specs are complete.
- Begin Takeoffs.
- Think About Labor Issues.
- Check Your Work.
- Assemble the Paperwork.
- Don’t Forget to Follow Up.
What is the K-factor for sprinklers?
The k-factor for a fire sprinkler is the discharge coefficient, or in normal human terms just relates to the amount of water that is permitted through the sprinkler. The k-factor is dependent upon the orifice diameter of the sprinkler – a low k-factor (such as K2.
What is pressure K-factor?
K-factor helps to calculate the discharge rate from fire sprinkler heads. It’s calculated in imperial units for the United States by using the flow in gallons per minute (gpm) and the pressure in PSI. Metric calculations use the flow in liters per minute and pressure in bar.
What is design density of sprinklers?
Density in sprinkler design refers. to the amount of water per square. foot (square meter) that the system. is intended to deliver each minute.
What is the minimum pressure for fire water lines?
The set pressure will typically be in the range 8–10 barg. Generally, the jockey pump will turn itself on and off depending on the header pressure. If the pump runs continuously its discharge should recirculate through a minimum flow bypass.

What is a Category 3 sprinkler system?
These categories range from 1-3. Category 1 covers individual dwellings to small blocks of flats (less than 18M high). Category 2 covers large blocks of flats (over 18M high) and small residential care homes (10 residents or less). Category 3 covers large residential care homes (more than 10 residents) to hostels.
