5/22/2018 API MPMS 11.2.1M (1984) Crude Oil CPL Calculation

2/4

CPL = 1/[1-(P*10^-6 Pe) * F]

F = EXP {A + B*T + C/(RH0)^2 + [D*T/(RHO)^2*]*10^-4}

MPMS 11.1M Where:

A, B, C, and D = constants.

T = temperature, in "C.

RHO = density, in grams per cubic centimetre

at 15C. 1/RHO is proportional

to molecular volume.
