What is meant by silt density index?

Silt Density Index (SDI) is an empirical test developed for measuring the rate of fouling of nano filtration (NF) or RO membranes. It represents the potential for fouling of the membranes by finely suspended particles present in feed water to the membranes.


What is the density in siltstone?

Silt is a mixture, not a pure substance. The density would depend on the mixture of minerals that make up the silt. Sand (quartz) has a density of about 2.5 g/cm3. If the silt is mostly sand then that would be a good approximation of the density.

How is T-score related to stiffness index in bone mineral density test?

The T-score is related to the Stiffness Index, because the Index is used to determine the T-score. This is an expression of structure, strength, and density.


What does the term density and refractive index mean?

The optical density of a medium is not the same as its physical density. The physical density of a material refers to the mass/volume ratio. Optical density determines how much a light wave is slowed down as it passes through a medium. The more optically dense a material is, the slower that a wave will move through the material.The refractive index is a measurement of optical density. A medium with a low optical density, would have also a low refractive index.For example air, having a low optical density has a refractive index of 1.0003, whereas water, with a higher optical density, has a higher refractive index of 1.333.

refractive index of glass is higher than refractive index of glass slab OR density of air is less than density of glass


What kind of density current is caused by muddy rapidly flowing mixture of sediment and water?

A turbidity current is a density current that occurs when mud or silt mixes with seawater. This is the result of the increase in the density of the water itself.
