# Small-gap leakage screening
# Scope: Laminar rectangular narrow-slot leakage; Newtonian fluid, no roughness/contact effects.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

gap = 10 um
width = 10 mm
length = 5 mm
pressure = 100 kPa
viscosity = 0.001 Pa*s

flow := width*gap^3*pressure/(12*viscosity*length) [mL/min]

check leakage budget: flow <= 2 mL/min

scenario alternative: gap = 8 um
