SERVICE MODULE RCS LOADING PARAMETERS AND CALCULATIONS - QUAD D
T. Fuel Density (Ib/in3); solve
equation (i) below where T -
Temperature @ P above
FV Parameters for Combined
Primary and Secondary Fuel Tanks
U. Volume of GHE-GSE Line (in 3)
V. Volume of S/C GHE Line (in 3)
W. GSE Line Pressure (PSIG)
X. Bladder Pressure (PSIG)
Y. Stabilized Equilibrium
Pressure (PSIG)
Z. Specification PV Value @
Temperature P above (Ib)
Maximum
Minimum
ZI. PV calculated fuel load (ib)
Solve equations (2) and (3) below
by substituting the values con-
tained in the above indicated
steps where UV = Volume or tanked
gas (in 3) in the primary tank and
FL = PV calculated fuel load.
Z2. Specification Nominal
value @ temperature H above (lb)
Z3. Total fuel load (ib) ±0.7
(Item F plus Item ZI)
(i) Fuel density = 0.0329456 - •
(0.186979)(I0-4)(T)
(2) U V = U _ - (C + S) (Y + X + 14.7)
F
_3) FL = T (O + R - Uv + V + B + B1 - ¥ )
Secondary Fuel
Load by P.V. (ib)
*Z4.
*If secondary fuel load is determined by P.V. calculation, then in
Equation Three (3), substitute item Z4 for item F.
