Calculates the minimum insulation thickness needed so that humid air flowing through the pipe does not reach its dew point before the outlet, and shows the resulting temperature profile and heat loss.
Process Inputs
Used to compute the dew point of the inlet air (Magnus-Tetens approximation). Only physically meaningful up to about 100°C.
Insulation thickness is no longer an input – it is calculated (see results) as the minimum thickness that keeps the outlet air temperature at or above its dew point, so no condensation occurs by the end of the pipe.
Ambient Conditions
Free convection in still air ≈ 5–10; light air movement ≈ 15–25; forced convection / wind ≈ 25–50 W/(m²·K).
