Calculate equivalent P.bv and dynamic gas force from press test to determine preload on the icpsring. However, the act gas force will be approx 1-2 lbs higher than calculated due to thermal expansion of the hot ctg oi.  For a more accurate icspr preload, set preload so the calculated icspr force is about 2lbs less than actual.         vs_fics           kg/mm   icspr rate zero indicates the icspr did not have prel-->     mm   icspr prel (+nu . . not zero)               mm   ctg rod dia           mm   icpist dia             mm   icrod dia           mm   dyno test stroke             mm   dyno prel              mm   9 oclock gas test position       Results             907.92     mm^2   icpist area       78.54     mm^2   icrod area          829.38     mm^2   icpist area - icrod area       126.2     mm   ctg rod stroke       113.1     mm2   ctg rod area       14272.88     mm3   ctg rod vol      17.21     mm    icpist stroke         17.21     mm   icspr stroke (icpist_stroke + prel)         0     kgf   from icspr       icspr force   0 lbf icpistArea - icrodArea   1.286 inch2 in2 ctg rod area   0.1753 inch2   0     psi   P.bv psi   0     lbf   equiv dynamic gas force          (DFF 1 leg, SFF not halved)   [openDynoFk__press_calc_gasforce_bu_7-7-25.php]
