Explanation:
From the question we are told that
The number of identical drippers is n = 60
The diameter of each hole in each dripper is
The diameter of the main pipe is
The speed at which the water is flowing is
Generally the amount of water used in one hour = 3600 seconds is mathematically represented as
Here A is the area of the main pipe with value
=>

Answer:
the resulting angular speed after she pulls her hand inwards in (rad/s) is 27.02 rad/s
Explanation:
Given that :
the initial angular speed
Initial rotational inertia
Final angular speed
Final rotational inertia
According to conservation of momentum :
Initial momentum = final momentum
To rad/s ; we have:
Therefore the resulting angular speed after she pulls her hand inwards in (rad/s) = 27.02 rad/s
