Effective Size definition

Effective Size means the size of granular media such that 10 percent by weight of the media is finer than the size specified.
Effective Size or “D10“ means particle diameter of which ten per cent of the sample is finer by weight as determined by a sieve analysis.
Effective Size means the size of screen opening where 90 percent by weight of a sample of sand is retained on the screen and 10 percent passes through the screen. This size is usually expressed in millimeters.
