First,
where is density,
is mass, and
is volume. We can compute the volume of the roll:
When the roll is unfurled, the aluminum will be a rectangular box (a very thin one), so its volume will be the product of the given area and its thickness . Note that we're assuming the given area is not the actual total surface area of the aluminum box, but just the area of the largest face (i.e. the area of one side of the unrolled sheet of aluminum).
So we have
where is the given area, so
If we're taking significant digits into account, the volume we found would have been , in turn making the thickness
.
Answer:
a
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
=>
=>
