Enter the oven dry weight (g), the SSD weight (g), and the weight in water (g) into the Bulk Specific Gravity Calculator. The calculator will evaluate the Bulk Specific Gravity.
Bulk Specific Gravity Formula
The following formula is used to calculate the Bulk Specific Gravity.
GSB = DW / (SSD - WW)
Variables:
- GSB is the Bulk Specific Gravity ( )
- DW is the oven dry weight (g)
- SSD is the SSD weight (g)
- WW is the weight in water (g)
To calculate the bulk specific gravity, divide the oven dry weight by the difference between the SSD weight and the weight in water.
How to Calculate Bulk Specific Gravity?
The following steps outline how to calculate the Bulk Specific Gravity.
- First, determine the oven dry weight (g).
- Next, determine the SSD weight (g).
- Next, determine the weight in water (g).
- Next, gather the formula from above = GSB = DW / (SSD – WW).
- Finally, calculate the Bulk Specific Gravity.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem:
Use the following variables as an example problem to test your knowledge.
oven dry weight (g) = 50
SSD weight (g) = 30
weight in water (g) = 20
GSB = DW / (SSD – WW) = ?
