Antifreeze systems that contain a backflow preventer between the antifreeze piping and the wet pipe system must be
equipped with
Antifreeze systems equipped with a backflow preventer must include an expansion chamber to accommodate the expansion of the antifreeze solution due to temperature changes. This prevents excessive pressure buildup that could damage the system or cause unintended discharge.
An existing sprinkler system in a 25 ft (1.5 m) tall building is found to be designed using K-8.0 (115) high temperature
control mode density/area (CMDA) sprinklers with a design criteria of 0.35 gpm/ft2 (13.3 mm/min) over
2000 ft2 (186 m2). What is the maximum storage height permitted for double-row rack storage with 8 ft (2.4 m) aisles
of a nonencapsulated Class IV commodity?
The maximum storage height permitted for double-row rack storage of a nonencapsulated Class IV commodity with the specified design criteria would likely be around 16.5 feet. This takes into account the density and area coverage required for protecting Class IV commodities.
What is the equivalent length of a 45 elbow of 6 in (150 mm) Schedule 10 pipe?
The equivalent length of a 45 elbow for 6 in Schedule 10 pipe is often considered to be around 11.8 ft, accounting for friction loss and the impact on water flow. This equivalent length helps in hydraulic calculations to ensure the sprinkler system meets the required design criteria for pressure and flow.
In an existing system, the vertical clearance between a high volume low speed (HVLS) fan and a sprinkler shall be
NFPA 13 requires a minimum vertical clearance between HVLS fans and sprinklers to prevent interference with the sprinkler spray pattern. A 24 in. (600 mm) clearance is commonly recommended to ensure that the fan does not disrupt the distribution of water in the event of a fire.
After reviewing an existing sprinkler system, it was determined that sprinklers were installed using NFPA 13 using the Ordinary Hazard Pipe Schedule method. The highest elevation of sprinklers is 28 ft (8.53m) and the system is fully monitored as specified by NFPA 13. What is the minimum pressure and flow required?
For a system using the Ordinary Hazard Pipe Schedule method, the minimum pressure and flow required are typically based on the system's design criteria, which for a system fully monitored as specified by NFPA 13 and with the highest elevation of sprinklers at 28 ft, would be around 500 gpm at 27 psi.
