SPS PROPELLANT LOAD CALCULATION
FUEL
1. Enter SPS Quantity Readout at 110 PSIA (Table 3.1-12 100.8
Item C - Percent)
2. Use Fisures 4.1-3 and 4.1-4 to obtain pro-
pellant load for above quanClCy readout,
3. Nominal propellant density at loading temperature
(use temperature - density graph below) (ib/ft3) 56.46
4. Cubic feet of propellant (item 2 divided by item 3) 277.86
5. Calculated density from Table 3.1-12 item f (lb/ft 3) 56.37
6. Adjustment due to PUGS zero adjust (pounds)
?. Resulting actual propellant load (item 4 times
item 5, less item 6) (pounds)
