Drinking Fountain Water Speed

APPH12-JRP1QS

You go to a water fountain and note that the trajectory of the water coming from the nozzle has a range of 6.00 centimeters at a level range. You estimate that the angle that the water makes coming out of the nozzle is 70.0 degrees with the horizontal.

The nozzle has a diameter of 0.50 cm and the pipe feeding the fountain has a diameter of 1.50 cm.

Based on this information, which of the following is the best value for is the water moving in the pipe that leads to the nozzle?

A

The speed of the water in the pipe feeding the fountain is $0.11\text{ m/s}$.

B

The speed of the water in the pipe feeding the fountain is $0.32\text{ m/s}$.

C

The speed of the water in the pipe feeding the fountain is $1.06\text{ m/s}$.

D

The speed of the water in the pipe feeding the fountain is $8.6\text{ m/s}$.
