# Convective heat transfer
# Scope: Newton cooling with a supplied heat-transfer coefficient.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

coefficient = 10 W/(m^2*K)
area = 0.2 m^2
difference = 30 K

heat := coefficient*area*difference [W]

check heat rejection target: heat >= 50 W

scenario alternative: coefficient = 8 W/(m^2*K)
