The Gravimetric Water Content calculator computes the percentage of water verses solids.
INSTRUCTIONS: Choose units and enter the following:
- (WW) Mass of Water Content
- (WS) Mass of Solids Content
Gravimetric Water Content (θg): The calculator returns the percentage of water.
The Math / Science
The gravimetric water content θg is the mass of the water contained in a sample volume divided by the mass of the solid (dry mass equivalent) in that same volume. The formula for gravimetric water content used in this calculator is:
θg = WW / WS
where:
- θg = Gravimetric water content percentage
- WW = Mass of Water
- WS = Mass of Solids
In engineering application the porosity is used to indicate a tendency of a material to expand or contract. A high porosity percentage is likely to be seen in loose soils which then will contract under pressure or added loads. A low porosity percentage represents a material that is dense. This porosity percentage affects how fluids will flow through a medium or how particulates can move through the medium.
