P, P, and P , may be in either pounds per square inch gage or pounds per square inch absolute, but both must be in the same units As an example, calculate the volume at equilibrium pressure of lo00 barrels (V,) of a material with a relative density (6OW6O"F) of 0.5297 metered under*a pressure of 500 pounds per square inch at a temperature of 55.1"F.The equilibrium pressure (P,) for this material at 55.1T is 45 pounds per square inch The rounded relative density and temperature values of 0.530 and 550°F yield an A factor of 35,641and a B factorof 5.516.Thecompressibiiityfactor ( F ) is Calculated as follows: 11.2.2.3 TYPE OF STANDARD AND LIMITS The actual standard is the printed table of 224 pages that follows this text The increments used in the table are OST and 0.002 relative density Interpolation to 0.001 relative density is allowed Compressibilities are in the usual units of reciprocal pounds per square inch but are calculated from two terms, A and B, and the pressure difference from equilibrium, D , This is necessary to obtain the desired accuracy F + = 1/(A D, * B ) = 1/[35,641 (500 - 45) * 5.5161 + = O.oooO2621 The value for F is rounded to the eighth decimal place, to the maximum of four significant digits ~ ~~ S T D S A P I I P E T R O MPMS L L - - - f N G L L78b 2 05b2507 70b m I) a O t a -
