Newton's Law of Cooling Calculator

Calculate convective heat transfer Q = h × A × (T_s − T_∞). Check lumped system validity using Biot number Bi = hL/k < 0.1 for uniform temperature assumption.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)

How It Works

Calculate convective heat transfer Q = h × A × (T_s − T_∞). Check lumped system validity using Biot number Bi = hL/k < 0.1 for uniform temperature assumption

Each component has a specific meaning:

  • Biot number Bi = hL/k < 0 — The biot number bi = hl/k < 0 recorded for the patient or scenario being assessed.

Note: Interpret the newton cooling result against the clinical thresholds and context described above.

How to Use

Enter the Biot number Bi = hL/k < 0 for the patient or scenario you are assessing. Calculate convective heat transfer Q = h × A × (T_s − T_∞). Check lumped system validity using Biot number Bi = hL/k < 0.1 for uniform temperature assumption. Use the newton cooling result to inform your clinical assessment.
