Answer:
The velocity of the flow at point 1 is nine times greater than the velocity at point 2.
Explanation:
We know that the same volume of water entering through point 1 must exit through point 2.
The volume of water per unit of time or the volumetric flow is defined by:
[tex]V_{flow}=v*A\\ where:\\V_{flow}= flow [m^3/s]\\v=velocity[m/s]\\A=area [m^2][/tex]
If [tex]A_{2}=9*A_{1} \\[/tex]
therefore
[tex]v_{1} *A_{1} = v_{2} *A_{2} \\v_{1} *A_{1} = v_{2} *9A_{1} \\\\v_{1} = 9v_{2} \\[/tex]
