The following table should be used to determine the amount of propellant to
be off-loaded from a full condition to 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)
D. Correction for tank pressure (ib)
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)
H. Delta density (GM/CC) (Item F-G)
3I. 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
M. Quantity required to fill RCS manifolds
N. Quantity to be off-loaded (Item K-L-M)
NOTES:
ILoading temperature correction will always be negative;
2To calculate the nominal density solve the following 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)
3Correction for measured density may be either positive or negative.
