TABLE3.4-11
SPS PROPELLANT LOAD CALCULATIONS
i. Enter SPS Quantity Readout at Ii0 PSIA (Table 3.4-12
Item C - Percent)
2. Use Figures 4.1-3 and 4.1-4 to obtain propellant
load for above quantity readout.
3. Nominal propellant density at loading temperature
(use temperature - density graph below) (ib/ft 3)
4. Cubic feet of propellant (Item 2 divided by Item 3)
5. Calculated density from Table 3.4-12 Item F (ib/ft 3)
6. Adjustment due to PUGS zero adjust (pounds)
7. Resulting actual propellant load (Item 4 times
Item 5, less Item 6) (pounds)
