About Fire Hydrant Flow Calculator

This engineering tool computes the water flow rate from a fire hydrant using the standard theoretical discharge formula. Input the pitot gauge reading (psi), internal diameter of the nozzle, and select the appropriate discharge coefficient based on the nozzle's shape. Designed for civil engineers and fire protection evaluation.
