Water Fountain Height

APPH12-BMK5Z9

Four decorative water fountains are in a garden. They are each connected to a pipe in the base and the top of each fountain has a single nozzle. When the water flows in the pipe, water shoots straight up into the air.

Although the pipes have different diameters, the velocity of the water in each pipe is constant at $5 \text{ m/s}$.

Which fountain shoots the water the highest into the air?

A

The diameter of the pipe is $2.50\text{ cm}$ and the diameter of the nozzle is $1.00\text{ cm}$.

B

The diameter of the pipe is $2.00\text{ cm}$ and the diameter of the nozzle is $0.60\text{ cm}$.

C

The diameter of the pipe is $3.00\text{ cm}$ and the diameter of the nozzle is $1.00\text{ cm}$.

D

The diameter of the pipe is $3.50\text{ cm}$ and the diameter of the nozzle is $1.20\text{ cm}$.
