A batting average of .333 represents a player's ratio of hits to at-bats in baseball. It means that the player gets a hit approximately 33.3% of the time they come up to bat. A .333 batting average is generally considered very good and indicates a high level of skill and consistency at the plate.

the foul lines come directly to the point on the back of home plate. that is why a ball off the plate is a fair ball
25" equals 635mm
You can measure defects on a plate with a 3-D surface map. To mention defects on a plate in a report you would want to include the shape, surface roughness, and surface finish of the plate.
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
Arithmetic Average Roughness Height. It's unit is in microns.
Acronym: AARH Definition: Arithmetic Average Roughness Height
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.
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..
In engineering terms, Ra is the arithmetic meaning for roughness of a surface, and is also referred to as arithmetic average.
The Absolute roughness, e, of copper is 1.5 microns The relative roughness is just e/D
The director of Necessary Roughness was Stan Dragoti.
The difference between roughness and flatness is that one, flatness, is the shape of an object. Roughness is the surface or texture of an object.
