What are simpler, quicker methods for performing hydraulic calculations called?

The term that best describes simpler, quicker methods for performing hydraulic calculations is "Fireground hydraulics." This concept encompasses techniques that are specifically tailored to be applied swiftly in the field, allowing fire service personnel to make effective water flow and pressure calculations at the scene of a fire. These methods are essential for ensuring efficient fire suppression operations, particularly when dealing with time-sensitive situations.

Fireground hydraulics focuses on practical application rather than complex mathematical formulas, making it crucial for firefighters who need to quickly assess and respond to fluid dynamics in an emergency context. This approach includes understanding how to use hose configurations, nozzles, and other equipment to achieve the desired flow rates and pressure based on immediate fireground conditions.

Other terms mentioned may pertain to concepts within hydraulic calculations but do not specifically capture the essence of expedited methods used directly at fire scenes. For instance, rapid fire calculations, field hydraulics, and basic flow strategies might refer to broader or different elements of hydraulic theory or practice rather than the specific, rapid methods used in active firefighting scenarios.
