# Melting and latent-heat storage
# Scope: Sensible heating plus latent heat at fixed properties; losses omitted.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

mass = 0.5 kg
heatCapacity = 4200 J/(kg*K)
rise = 20 K
latent = 334000 J/kg
power = 500 W

energy := mass*(heatCapacity*rise+latent) [J]
duration := energy/power [s]

check process time budget: duration <= 600.0 s

scenario alternative: mass = 0.4 kg
