Final above-ambient temperature (K)
Lumped constant heat capacity and Newton cooling: C dθ/dt=P−Hθ; adiabatic branch when H=0.
Temperature change (K)
Lumped constant heat capacity and Newton cooling: C dθ/dt=P−Hθ; adiabatic branch when H=0.

Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; Lumped constant heat capacity and Newton cooling: C dθ/dt=P−Hθ; adiabatic branch when H=0. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
