Trace heating design
The calculation of heat losses is done with the following
formula:
Qv= (2 * Pi * lambda * (Th
- Tmin)) / (ln * (D/d))
1. Design Data

The default value are validated for calculations within Europe and
usable upto a wind speed of 5m/s (18km/h; Beaufaut No.3).The
thermal conductivity of 0,052W/mK is based on
mineralwool, change this value if you want to use other insulation
material, please (e.g.: PU-foam 0,028W/mK)
Please take care that you use the point instead of a comma
otherweise you will see NaN as a result
A hint for a suitable insualtion thickness is: Thickness
of insualtin approx. as thick as the pipe diameter.(e.g.: DN
50-> 50mm insulation thickness
Please take care to the temperature dependence of insulationmaterial
(especially for hight temperatures)
