2024年1月12日 · Fire Flow When new buildings are built, the Fire Code requires a water supply be provided to meet the fire flow for that building. Fire flow is defined as the “flow rate of a …

• To obtain satisfactory test results of theoretical calculation of expected flows or rated capacities, sufficient discharge should be achieved to cause a drop in pressure at the residual hydrant of …

Projected available flows calculated at 20 psi residual, or ½ the static pressure for low pressure hydrants having static pressures of less than 40 psi. This calculator is based on established …

Chart Values have been rounded to the nearest 5 GPM.

The Hydrant Flow Test Calculator measures the rated capacity at 20 psi of a fire hydrant. The rated capacity calculation is useful in determining the total water supply at a given point in the …
