The surface roughness of the Si surface was the main evaluation index, and the material removal rate was the secondary evaluation index. An experiment was designed using the Taguchi method to analyze the effects of … WebDetermine the friction factor (f D) for fluid flow in a pipe of 700mm in diameter that has the Reynolds number of 50 000 000 and an absolute roughness of 0.035 mm. . Solution: The relative roughness is equal to ε = 0.035 / 700 = 5 x 10-5.Using the Moody Chart, a Reynolds number of 50 000 000 intersects the curve corresponding to a relative roughness of 5 x …
WebFig. 9.22 shows the change of the surface roughness ratio with normalized normal pressure. R a ′ is the surface roughness after flattening while R a is the initial surface roughness. It is clear that the roughness decreases with an increase of normal pressure because the roll flattens the asperities and peaks much more. WebDescription.
