# O-ring squeeze and gland depth
# Scope: Nominal cross-section compression fraction; no elastomer/pressure qualification.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

crossSection = 3 mm
glandDepth = 2.4 mm

squeeze := (crossSection-glandDepth)/crossSection

check example squeeze upper bound: squeeze <= 0.3

scenario alternative: crossSection = 2.4 mm
