NOTES:
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 calculeted off-load is _0.5 pounds per
weigh tank.
A. Final tank pressure at overfill (PSIG) 49.3 51.9
B. Propellant loading temperature (OF) 69.2 67.4
C. Nominal overfill quantity (Ib) 2074.1 3317,7
D. Correction for tank pressure (ib) 0,8 it8
Fuel - 0.09 (Item A-40)
Oxidizer - 0.15 (Item A-40)
IE. Correction for loading temperature (Ib)

J. Propellant in GSE i_6 4.8
K. Overfill quantity (C+D+E+I+J) 2071ti 3315.9
L. Target loading 2014,4 __9228.2
H. Quantity required to fill RCS manifolds 7.9 12.7
N. Quantity to be off-loaded (Items K-L-M) 48.8 75.0
1Load::ng temperature correction will always be negative.
2To calculate the nominal density solve the followingoequation where T-
teomperature in °C of the measured density (usually 4 C for oxidiser 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)
NoB,trial oxidizer demJity - 1.491539-0.0022832 ('C)
3Correction for measured density amy be either positive or nelative.
