If a tectonic plate has moved 125 cm in 25 years what is its average rate of movement in cm per year?
5 cm/year
What is a 333 batting average?
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.

How do you measure and mention defects on plate?
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.
What is the Relative roughness factor of a fiberglass pipe?
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
What is surface roughness tester?
A surface roughness tester is a device used to measure the roughness of a surface by analyzing the texture and profile of the surface irregularities. It provides numerical data, such as Ra and Rz values, which describe the average roughness and peak-to-valley height of the surface respectively. These measurements are important for ensuring the quality and performance of manufactured components.
What is aarh in valve finish?
Arithmetic Average Roughness Height. It's unit is in microns.
What is AARH in flange finish?
Acronym: AARH Definition: Arithmetic Average Roughness Height
What is means by RA?
In engineering terms, Ra is the arithmetic meaning for roughness of a surface, and is also referred to as arithmetic average.
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
Which is rougher 15 Ra or 20 Ra Ra is Roughness average a term used in passivation?
20 ra is worse
