Density From API Formula
The following formula is used to calculate the Density From API.
D = 141.5/(API+131.5) * 998.9
- Where D is the Density From API (kg/m^3)
- API is the API
How to Calculate Density From API?
The following example problems outline how to calculate Density From API.
Example Problem #1:
- First, determine the API.
- The API is given as: 55.
- Finally, calculate the Density From API using the equation above:
D = 141.5/(API+131.5) * 998.9
The values given above are inserted into the equation below:
D = 141.5/(55+131.5) * 998.9 = 757.878 (kg/m^3)
Example Problem #2:
For this problem, the variables needed are provided below:
API = 65
This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.
D = 141.5/(API+131.5) * 998.9 = ?
