An example of a system with decreasing gravitational potential energy is a ball in free fall.
At its initial height h, the ball has a gravitational potential energy equal to
where m is the ball mass and g is the gravitational acceleration. As the ball falls toward the ground, its height h decreases, and so its gravitational potential energy decreases as well, according to the formula
where h' is the new height of the ball.

b
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
=>
=>
So
=>
=>
Generally the area of the drippers is mathematically represented as
=>
=>
Generally from continuity equation we have that
=>
=>
