Most of the calculations proposed in this paragraph require iterations; for this reason, it is preferable to program the following algorithms to obtain faster and more accurate results.
Generally speaking, the thermal power balance of a conductor in steady state (thermal equilibrium) is written as follows: Heating power = Dissipation power( 1 )PJoule + Psunshine = Pconvection + Pradiation PJ + Ps = Pc + Pray
