How the roughness of sandpaper affect its ability to smooth various surfaces?
The rougher the sandpaper, the more it takes off the material being sanded. The finer the grade (smoother) the smoother the finish will be. Rougher grades are used at the beginning to remove tool marks and shape the material, and you gradually work up to the finer grades for finish work. The very finest grades are used to polish the finish.

What is surface roughness tester?
surface roughness tester is the machine which used to measure the roughness of the surface using probes... roughness is nothing but the frictional force applied by the surface to the adjacent surface.. if roughness increases the amount of frictional force increases..
What are examples of low friction materials?
Some examples of relatively high friction surfaces are: sand paper, grass, and asphalt. In general, the rougher the surface, the more friction it has.
Does two pieces of sandpaper have more friction or two pieces of notebook paper?
the sandpaper has more friction
How do you use roughness in a sentence?
He would have been a more successful orator, if not for his roughness in a sentence. The roughness of the shale tore a hole in my pants when I slid down the embankment. I use sandpaper to reduce the roughness of the cabinet's surfaces.
What does the letter on sandpaper mean?
It indicates the roughness of the paper, like f is for fine.

What is the simile the author used to describe Timothy voice and words in the cay?
The author described Timothy's voice as being "as deep as the sea and as rough as sandpaper," comparing it to the qualities of depth and roughness found in the sea and sandpaper. This simile portrays Timothy's voice as strong and textured, reflecting his character and experiences.
How do rocks get a sandpaper texture?
The texture of a rock is determined by the rate it takes the molten to cool to form the rock.
How do you read moody's diagram?
To determine the frictional factor, find the relative roughness value for the pipe on the right. Then locate the pipes Reynolds number on the bottom. Follow the relative roughness curve to where it crosses the determined Reynolds number. Now at that point project a straight line to the left, the number determined on the left is the frictional factor.
What is relative roughness?
Relative roughness is a measure of the surface roughness of pipe surfaces. It is the size of the roughness scaled by the diameter of the pipe or duct. Rel Roughness=e/D; where e is the measurement of the surface roughness and D is the diameter of the pipe. It is mainly used for calculating head losses in piping systems.

What is the expected relative roughness of copper?
The Absolute roughness, e, of copper is 1.5 microns The relative roughness is just e/D
Is sandpaper a dependent variable?
I really can not answer this question. Variables represent outcomes, properties, qualities or events. A good example of a dependent variable related to sandpaper is the amount of wood is removes. Now, this variable will depend on many factors. Can you think of some? a) The amount of time that you sand b) The roughness of the sandpaper c) The size of the piece of wood you are sanding d) The hardness of the wood you are sanding e) The pressure that you apply when you are sanding I can come up with many more independent variables if I include sanding by hand or using a machine.
