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 par welsh tank.

NOTES:
ILoading temperature correction will always be negative,
2To calculate the nominal density solve the followin8 equation where
T-temperature in "C of the measured density (usually &eC for oxidizer
and 25"C for fuel). Th£a equation is valid for 14.7 PSIA. Therefore.
the measured density must also be at 14.7 PSIA.
