Volume Percent of Porosity Specific Yield and Specific Retention

Go Volume Percent of Porosity = Specific Yield Percentage+Specific Retention Percentage

Specific Retention given Porosity

Go Specific Retention Percentage = Volume Percent of Porosity-Specific Yield Percentage

Specific Yield given Porosity

Go Specific Yield Percentage = Volume Percent of Porosity-Specific Retention Percentage

Volume of Water Drained by Gravity given Specific Yield

Go Volume of water drained by gravity = (Specific Yield Percentage*Total Volume)/100

Specific Yield given Total Volume

Go Specific Yield Percentage = (Volume of water drained by gravity/Total Volume)*100

Total Volume given Specific Yield

Go Total Volume = (Volume of water drained by gravity/Specific Yield Percentage)*100

Volume of Water Retained given Specific Retention

Go Volume of Water retained = (Total Volume*Specific Retention Percentage)/100

Specific Retention given Total Volume

Go Specific Retention Percentage = (Volume of Water retained/Total Volume)*100

Total Volume given Specific Retention

Go Total Volume = (Volume of Water retained/Specific Retention Percentage)*100

Specific Retention given Porosity Formula

Specific Retention Percentage = Volume Percent of Porosity-Specific Yield Percentage
%S_r = η_v-%S_y

What is Specific Retention?

The ratio of the volume of water that a given body of rock or soil will hold against the pull of gravity to the volume of the body itself. It is usually expressed as a percentage.

How to Calculate Specific Retention given Porosity?

Specific Retention given Porosity calculator uses Specific Retention Percentage = Volume Percent of Porosity-Specific Yield Percentage to calculate the Specific Retention Percentage, The Specific Retention given Porosity is defined as the volume fraction of water that is held back by adhesion and capillary forces when an aquifer is drained. Specific Retention Percentage is denoted by %S_r symbol.

How to calculate Specific Retention given Porosity using this online calculator? To use this online calculator for Specific Retention given Porosity, enter Volume Percent of Porosity (η_v) & Specific Yield Percentage (%S_y) and hit the calculate button. Here is how the Specific Retention given Porosity calculation can be explained with given input values -> 10 = 25-15.
