Relative Density Formula
The following formula is used to calculate the Relative Density.
RD = ds / dr
- Where RD is the Relative Density ((none))
- ds is the density of the substance (kg/m^3)
- dr is the density of the reference (kg/m^3)
How to Calculate Relative Density?
The following example problems outline how to calculate Relative Density.
Example Problem #1:
- First, determine the density of the substance (kg/m^3).
- The density of the substance (kg/m^3) is given as: 80.
- Next, determine the density of the reference (kg/m^3).
- The density of the reference (kg/m^3) is provided as: 20.
- Finally, calculate the Relative Density using the equation above:
RD = ds / dr
The values given above are inserted into the equation below:
RD = 80 / 20 = 4 ((none))
Example Problem #2:
For this problem, the variables needed are provided below:
density of the substance (kg/m^3) = 30
density of the reference (kg/m^3) = 100
This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.
RD = ds / dr = ?
