The following table should be used to determine the amount of propellant
to be off-loaded from a full condition Co arrive at the indicated load.
The allowable tolerance for the calculated off-load is +0.5 pounds per
weigh tank.
A. Final tank pressure at overfill (PSIG)
B. Propellant loading temperature ("F)
C. Nominal overfill quantity (Ib) 2072.3
D. Correction for tank pressure (ib)
A Fuel - 0.09 (Item A-40)
Oxidizer = 0.15 (Item A-40)
IE. Correction for loading temperature (ib)
Fuel = -1.16 (Item B-65)
Oxidizer - -2.84 (Item B-65)
2F. Measured density (GM/CC)
2G. Nominal density (GM/CC) 0.8994
H. Delta density (GM/CC) (Item F-G)
31. Correction for measured density
Fuel = 2300 (Item H)
Oxidizer = 2300 (Item H)
J. Propellant in GSE
K. Overfill quantity (C+D+E+I+J)
L. Target loading 2006.7
M. Quantity required to fill RCS manifolds
N. Quantity to be off-loaded (Items K-L-M)

ILoadlng temperature correction will always be negative.
2To calculate the nominal density solve the followlng equation where T-
temperature in °C of the measured density (usually 4°C for oxidizer and
25°C for fuel). This equation is valid for 14.7 PSIA. Therefore. the
measured density must also be at 14.7 PSIA.
Nominal fuel density = 0.922904-0.0009377 (*C)
Nominal oxidizer density - 1.491539-0.0022832 (°C)
3Correctlon for measured density may be either positive or negative.
