FIRE FLOW. The flow rate of a water supply, measured at 20 pounds per square inch (psi) (138 kPa) residual pressure, that is available for fire fighting. FIRE-FLOW CALCULATION AREA. The floor area, in square feet (m2), used to determine the required fire flow. SECTION B103 MODIFICATIONS B103.1 Decreases. P Fire Flow is formally defined as the "flow rate of a water supply, measured at 20 psi (138 kPa), that is available for fire fighting." (IFC 200-2018 Appendix B Section B102) Fire flow is used to determine the quality of a water supply to an area. It's used as an aid to determine pipe size and arrangements to delivery water to a specific area. Fire flow formulas have a wide range of use, from the firefighter to the chief officer. Practice using the formulas to determine fire flows for structures in your response area. As you become. The IFC method employs a charts ensure lists the minimum flow based at the construction type and size of the setup or what is called the "fire flow calculation area." The "fire flow calculation area" is the sum of all floor area between firewalls with no openings, or, in fire resistive construction, the sum of an area of the three.

The equation EP = NP + FL + APP + ELEV is the basic equation every pump operator needs to calculate when operating the fire pump. Today, many pump panels have flow meters that allow the pump. A fire hydrant flow test is a process of flowing water out of at least one fire hydrant while obtaining the required pressures (static, residual, and pitot) needed to calculate the amount of water in gallons per minute (GPM) that the water system is capable of providing between the tested hydrants. FTS allows you to effectively and efficiently.
