Answer:
Water leaves the sprinkler at a speed of 2.322 m/sec
Explanation:
We have given internal diameter of the garden [tex]d_1=1.1cm[/tex]
Speed of water in the hose is [tex]v_1=0.95m/sec[/tex]
Number of holes n = 22
Diameter of each holes [tex]d_2=15cm[/tex]
According to continuity equation [tex]A_1v_1=A_2v_2[/tex]
[tex]d_1^2\times v_1=22\times d_2^2v_2[/tex]
[tex]1.1^2\times 0.95=22\times 0.15^2\times v_2[/tex]
[tex]v_2=2.322m/sec[/tex]
So water leaves the sprinkler at a speed of 2.322 m/sec
