Answer:
The velocity of the water at the 8 cm section is 9 times the velocity of the water at 24 cm section.
Explanation:
For this question, we use the equation of continuity of an non-compressible fluid in a pipe
[tex]A_{1} v_{1} =A_{2} v_{2}\\\\\pi r_{1}^{2}v^{2} = \pi r_{2}^{2}v^{2} \\\\\pi (24)^{2}v_{1} ^{2} = \pi (8)^{2}v_{2} ^{2}\\\\576v_{1} = 64v_{2}\\\\v_{2} = 9 v_{1}[/tex]
The velocity of the water at the 8 cm section is 9 times the velocity of the water at 24 cm section.
