eng.heat-convection Calculator
Calculates convective heat transfer rate from Newton's law of cooling using the heat transfer coefficient, area, and temperature difference. Natural convection h values range from 2–25 W/m²K; forced convection 25–250 W/m²K — the difference determines whether forced cooling is needed.
Inputs
H
Reference formula or conversion factor shown for context.
Area M2
Two-dimensional surface extent (m²). For complex shapes, break into simpler sub-shapes and sum.
Ts
Reference formula or conversion factor shown for context.
Tf
Reference formula or conversion factor shown for context.
Results
heat transfer rate (W)
Thermal energy exchanged per unit time (W). Increases with temperature difference, material conductivity, and surface area.
thermal resistance (K/W)
Opposition to heat flow (K/W). Higher = better insulation. Works like electrical resistance — resistances in series add, in parallel follow the reciprocal rule.
temperature difference (K)
The arithmetic difference between the two values.
heat flux (W/m^2)
The value at the specified point or condition.
Q = h*A*ΔT
