One instrument used to measure roughness of roads is the response type road roughness meters (RTRRMs)
Carbon is the main hardening element in steel. However, increasing the hardness decreases the ductility. Strength in this case is relative.
Hardness or toughness
Steel don't float on water because the density of steel is greater than the density of water.
Its a good conductor of heat.. which means it gets Hot easily... so there for makes a good cooking untensil :)
for turbulent flow in pipes the friction factor depends on Reynold's number as well as the inside roughness of the material.you could calculate the pipe inside roughness or the relative roughness by referring to the 'values of absolute roughness table'.relative roughness =ε/Dwhere,ε- absolute roughness.D- inside diameter of the pipe.for stainless steel the the absolute roughness value is 0.0018inches or 0.000045metre.you could substitute the value in the above formula and find out the relative roughnes.After doing this refer the Moody diagram to find out the friction factor for the values of Reynold's number and relative roughness.ε
The Absolute roughness, e, of copper is 1.5 microns The relative roughness is just e/D
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.
relative roughness is the average bump height divided by the same characteristic length (pipe diamter) the relative roughness is calculated by k/d, k=0.0015 and d being the diameter relative roughness is the average bump height divided by the same characteristic length (pipe diamter) the relative roughness is calculated by k/d, k=0.0015 and d being the diameter
The Relative Permeability of stainless steel is approximately 1. This is applicable to stainless steel with no or hardly any magnetic property.
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.
One can purchase a commercial steel storage building through structural manufacturers, including Hansen Pole Buildings and Standard Steel Buildings. One can also buy commercial steel storage buildings from private owners.

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..
Non-commercial refers to an activity or an entity which does not, involve commerce, at least relative to similar activities that do have a commercial objective or emphasis.
mild
The angle of the cutting tip used to machine mild steel on a lathe is 55 to 80 degrees depending on the surface roughness, size of the cut and type of finish required.
