Generally, the water output of each hydrant is calculated as 10 ~ 15L/s, that is, 36 ~ 54 tons per hour. When the flow rate of 100mm pipeline is 1.5 ~ 2m/s, the flow rate is about 40 ~ 60m3/h.

A full water column does not exceed 24 meters and 5000 cubic meters. Multi-storey warehouses, houses less than 54 meters and each unit

There are evacuation stairs, the installation height is 1. 1m, the tap pressure is less than 0, 5 is enlarged to 0, 7 is equipped with decompression device, the clearance is over 8m, the outlet is 0.35 water column 13m, and the other is 0.25 water column 10m.

One hydrant is 5 liters per second, and the water filling time of dry hydrant is 5 minutes. 120 square meters, this can be seen from the flow parameters of the pump, 1 10 pump, if the lift is 40 meters. The flow in one hour is about 120 tons of water.
