What is a sandpaper used for?
They are essentially used for surface preparation. Sandpaper is produced in a range of grit sizes and is used to remove material from surfaces, either to make them smoother (for example, in painting and wood finishing), to remove a layer of material (such as old paint), or sometimes to make the surface rougher (for example, as a preparation for gluing).
Answer:
Head loss = 28.03 m
Explanation:
According to Bernoulli's theorem for fluids we have
Applying this between the 2 given points we have
Here 
is the head loss that occurs
Since the pipe is horizantal we have 
Applying contunity equation between the 2 sections we get
Since the cross sectional area of the both the sections is same thus the speed
is also same
Using this information in the above equation of head loss we obtain
Applying values we get
Woah, that’s phenomenal! I can’t even draw a straight line with a ruler! How much time did that take you?
