Question

A pipe with a diameter of 2cm is attached to a garden hose with a nozzle.If the velocity of flow in the pipe is 2m/s, what is the velocity of the flow at the nozzle when it is adjusted to have a diameter of 4mm

Answer 1

Answer:

the velocity of the flow at the nozzle when it is adjusted to have a diameter of 4mm a pipe with a diameter of 2cm is attached to a garden hose with a nozzle. if the velocity of flow.

Answer 2

The velocity of the flow at the nozzle when it is adjusted is 50 m/s.

Explanation:

Use equation of continuity as

$A_1v_1=A_2v_2$

Here, $A_1$ is the enter area of the pipe, $A_2$ is the water exit area of the pipe and $v_1$ is the velocity of flow in the pipe.

Given $v_1=2m/s,A_1=\pi(1cm)^2,A_2=\pi(0.2cm)^2$

substitute the given values, we get

$2m/s\times\pi (1cm)^2=v_2\times\pi\times(0.2cm)^2$

$v_2=\frac{2m/s\times(1\times10^-^2m)^2}{(0.2\times10^-^2m)^2}$

$v_2=50m/s$

Thus, velocity of the flow at the nozzle when it is adjusted is 50 m/s.
