Member Function Documentation

◆ bore_si()

float feedtwin.model.segments.LineSegment.bore_si ( self) 
Flow diameter [m], or zero if the segment does not state one.

Definition at line 134 of file segments.py.

References feedtwin.comps.iec_gas.GasCv.bore, feedtwin.model.segments.Fitting.bore, and bore.

◆ has_curve()

bool feedtwin.model.segments.LineSegment.has_curve ( self)

Definition at line 130 of file segments.py.

References feedtwin.comps.elements.MeasuredElement.curve, and curve.

◆ stated_length()

float feedtwin.model.segments.LineSegment.stated_length ( self) 
The length as written [m], whatever its basis.

Definition at line 139 of file segments.py.

References feedtwin.model.segments.Fitting.length, length, gnss_frame_parser_t.length, and self_test_spi_frame_t.length.

◆ tube_length()

float feedtwin.model.segments.LineSegment.tube_length ( self) 
Straight tube in this segment [m], with fitting bodies removed.

With ``length_basis == "overall"`` the stated length runs end to end, so
each fitting's body less its thread engagement comes out -- otherwise the
fittings are paid for twice, once as K and once as the tube they
displace.

This refuses to guess. If the basis is overall and any fitting has no
body length, the stated length is returned whole; the reader has already
warned about it. A partial subtraction is a wrong number that looks
careful, which is worse than a stated one that is flagged.
