Ashower head has 20 circular openings, each with radius 1.0 mm. the shower head is connected to a pipe with radius 0.80 cm. if the speed of water in the pipe is 3.0 m/s, what is its speed as it exits the shower-head openings?

The speed as it exits the shower-head openings is 9.6 m/s.

Explanation:

Given that,

Radius

Number of circular = 20

Radius of pipe

Speed = 3.0 m/s

We need to calculate the area of circle

Using formula of area of circle

We need to calculate the speed

Using equation of continuity

Where, A =area of cross section

v = speed

Put the value in the equation

Hence, The speed as it exits the shower-head openings is 9.6 m/s.
