API for Crude at standard condition
API for Crude at standard condition
(OP)
i ask if the pressure have create effect at API value for crude oil as do temperature?
also if crude oil have API=33 at 33.3 psi and 70 F temp.
what this API will be at at 14.7 psi and 60 F temp (standard condition)
also if crude oil have API=33 at 33.3 psi and 70 F temp.
what this API will be at at 14.7 psi and 60 F temp (standard condition)

API comes from density at reference conditions so if your starting point is density measured at line temperature and pressure, then you need to apply these correction before you can convert to API degrees.

i don't have The Manual of Petroleum Measurement Standards
can any one check this conversion for me in it
rude oil have API=33 at 33.3 psi and 70 F temp.
what this API will be at at 14.7 psi and 60 F temp (standard condition)

In Your Case you should use Section 11.1.6.3 which gives the method to convert Volume and Density from Observed Condition to Alternate Condition. (standard condition means 60 DegF & 0 PSI)
Obs density: 33 API
Obs Pr = 33.3 Psi
obs Temp = 70 DegF
Alt Pr = 14.7 Psi
Alt Temp = 60 DegF
Result
Alt density = 32.26 API
