Flow-X General functions - fxAPI_Table5_1980
fxAPI_Table5_1980
°API (T) --> °API (60°F)
This function converts an API gravity value at the observed temperature to the API gravity value at
60°F.
The temperature conversion is according to API MPMS 11.1:1980 (API-2540), Tables 5A (Generalized
Crude Oils) and 5B (Refined Oil Products) and API MPMS 11.1 Chapter XIII Table 5D: 1984 (Lubricating
Oils).
The function provides the option to correct for readings taken from a hydrometer as specified in the
API-2540 standard.
