Answer 1

v2=15.027m/s

Step-by-step explanation:

If the speed of water in the pipe is 3.0 m/s, what is its speed as it exits the shower head openings?

could be the concluding part to this question.

therefore

form equation of continuity

dv/dt=
`a_(1) *v_(1) =a_(2) *v_(2)`

a_{1}=
`\pi`*r^2

pi*(9*10^-4)^2

2.54*10^-6

tere are 20 f them 20*

a1=5.08*10^-5

a2=pi*(9*10^-3)^2

a2*v2=pi*(9*10^-3)^2*3

7.63*10^-4=5.08*10^-5*V2

v2=15.027m/s
