Final answer:
The question involves Physics and concerns the computation of Reynolds numbers for a fire hose and nozzle to determine the nature of fluid flow, which in this case is likely turbulent according to typical Re values for pipe flow.
Step-by-step explanation:
The question relates to the topic of fluid dynamics within the field of Physics, specifically addressing the concept of turbulent flow in a fire hose and nozzle based on Reynolds number calculations. To determine whether the flow is turbulent, the Reynolds number must be calculated for both the fire hose and the nozzle. The Reynolds number (Re) is calculated using the formula Re = (v * D * ρ) / η, where v is the flow velocity, D is the diameter of the hose or nozzle, ρ (rho) is the density of the fluid, and η (eta) is the dynamic viscosity of the fluid. A high Reynolds number typically indicates turbulent flow, which is generally considered to be Re > 4000 for pipe flow. Given the data from your query, specific calculations would be needed to compute the flow velocities for the 6.40 cm diameter fire hose and the 3.00 cm diameter nozzle, using the provided flow rate, and then calculate the Reynolds numbers accordingly using water as the fluid in question with standard properties (density and dynamic viscosity).
