Help needed, 6 points! What are the appropriate values for outdoor and indoor fire-fighting water consumption?

Thread Content

The outdoor fire-fighting water flow rate is 25 L/s, and the indoor fire-fighting water flow rate is also 25 L/s. According to the Building Code GB50016-2006: 1. For outdoor fire protection, the water demand for outdoor fire hydrants should be calculated based on the requirements of the building with the highest fire water demand. 2. In tank areas, the cooling water demand should be determined by considering the surface area of the top of the largest tank involved in a fire (for horizontal tanks, this is the projected area), as well as the intensity of the cooling water supply. When the calculated water flow rate is less than 15 L/s, 15 L/s is still used ； 3. Indoor fire protection: There are no clear regulations regarding how to calculate the total fire-fighting water volume; seeking advice now? PS: Some colleagues use 50% of the cumulative value, while others refer to the outdoor fire-fighting water demand and take the maximum value. I’m not sure which approach is more reasonable Help needed, 6 points!
