What are hydraulic calculations used for in fire service?

Hydraulic calculations are essential in fire service operations as they determine the adequate water supply and pressure needed for effective firefighting. These calculations involve analyzing the flow of water through hoses, pipes, and various firefighting equipment, ensuring that when firefighters arrive at a scene, they have the necessary resources to combat the fire. By assessing factors such as water source availability, friction loss in hoses, and elevation changes, these calculations help to ensure that sufficient water reaches the fire with the required pressure, ultimately influencing the effectiveness of fire suppression efforts.

The correct understanding of hydraulic calculations directly correlates to operational readiness and safety during firefighting operations, making this knowledge crucial for firefighters and fire service professionals.
