Detailed Description

copv/n2_Z_lookup.csv covers the pressures a COPV holds, not only a propellant tank's.

The table stopped at 8.3 MPa; RegularGridInterpolator(fill_value=None) extrapolates linearly past
it, so the COPV solvers read Z 1.039 at 26 MPa and 300 K where CoolProp gives 1.105. On the LE4 (3)
stand's 1.312 kg in 4.619 L that put the charge at 3810 psia instead of 4141 (CoolProp, 300 K,
284 kg/m3), and shifted every COPV sizing in the Time-Series panel and Layer 2 by the same few
per cent. Extended to 60 MPa from CoolProp, the rows inside the old range untouched.
