# Steady conduction
# Scope: Steady one-dimensional slab conduction at constant conductivity.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

conductivity = 0.2 W/(m*K)
area = 1 m^2
thickness = 50 mm
difference = 20 K

resistance := thickness/(conductivity*area) [K/W]
heat := difference/resistance [W]

check heat loss budget: heat <= 100 W

scenario alternative: conductivity = 0.16 W/(m*K)
