Water Speed Ranking For a Hose

APPH12-97QRHW

A garden hose has a diameter of $2.50\text{ cm}$ and a rate of flow of $4.00\text{ m/s}$.

The nozzle that is attached to the hose has four different settings.

Which is the correct ranking of the velocity of the water coming out of the hose for these settings from high to low?

  • Nozzle A has a diameter of $0.60\text{ cm}$.

  • Nozzle B has a diameter of $1.20\text{ cm}$.

  • Nozzle C has a diameter of $1.00\text{ cm}$.

  • Nozzle D has a diameter of $0.80\text{ cm}$.
