Final answer:
The question asks about the required fire fighting equipment for boats of a certain size and discusses the practical application of physics in using a fire hose for firefighting, highlighting the significance of fluid dynamics in emergency situations.
Step-by-step explanation:
The question relates to the necessary fire fighting equipment aboard boats that measure between 6 and 9 meters in length. The mentioned equipment includes a fire extinguisher, a bucket, a hose, and a fire blanket. This question also involves understanding the physical properties of this equipment, particularly the hose, in a real-world context such as firefighting on boats or in a laboratory setting.
For example, calculating the fluid speed and flow rate in a given diameter hose is a practical application of physics that encompasses principles of fluid dynamics. If we consider a fire hose with a 9.00-cm diameter carrying 80.0 L of water per second, we can use the formula for the cross-sectional area of a pipe (Area = πd2/4) to find the flow speed and rate. Using this formula in physics helps ensure that firefighters are using the equipment effectively to fight fires, as seen during the Deepwater Horizon explosion where boats were utilized to combat the blaze.
