How Can Bernoulli's Principle be Related to Fire Hoses

Click For Summary

Discussion Overview

The discussion revolves around the application of Bernoulli's Principle to evaluate the effectiveness of fire hoses. Participants explore how various factors might influence the performance of fire hoses in extinguishing fires, with a focus on identifying independent variables for testing.

Discussion Character

  • Exploratory
  • Conceptual clarification

Main Points Raised

  • One participant suggests testing the effectiveness of fire hoses using Bernoulli's Principle and considers the width of the nozzle as a potential independent variable.
  • Another participant prompts for a definition of "effective" in the context of fire hoses.
  • A subsequent response defines "effective" as the ability to extinguish a fire in the shortest time possible.
  • Further inquiry is made into what specific factors determine the effectiveness of fire hoses in achieving this goal.

Areas of Agreement / Disagreement

Participants are seeking clarity on the definition of effectiveness, indicating a lack of consensus on this key term. The discussion remains unresolved regarding the specific factors that influence the effectiveness of fire hoses.

Contextual Notes

The discussion highlights the need for clear definitions and criteria when evaluating the effectiveness of fire hoses, which may depend on various physical and operational parameters.

Hello everybody:

I am trying to test, using Bernoulli's Principle, when firehoses are most effective.

I know this is extremely broad, but does anyone have any ideas for independent variables? I am thinking about the the width of the end piece of the nozzle...

Any help/guidance would be greatly appreciated.

Thank you in advance!

Ok; so what determines that?
