Specific gravity on API scale is given by the relation (where, G = specific gravity at 15.5°C) ?
Correct answer: B. °API = (141.5/G) - 131.5
- A. °API = 200(G - 1)
- B. °API = (141.5/G) - 131.5
- C. °API = (140/G) - 130
- D. °API = 145 - (145/G)
Explanation
The API gravity relation at 15.5°C (60°F) is °API = 141.5/G - 131.5, where G is the specific gravity. Lower specific gravity therefore corresponds to higher API gravity.
