Thank you for the answer. Which equation can be solved for T_ins and what do you mean with first order? Nusselt-number is T_ins dependent, and the heat flow equation above is a function of T_cond...
I have a cable which dissipates Q_total and I need to determine the surface temperature of the insulation T_ins and the surface temperature of the conductor T_cond.
There is an insulating layer with the thermal resistance R_cond and the convective thermal resistance R_conv. The radiation...
I have the following problem: A pipe shall have a constant surface temperature, whereby it gets elevated (from mean sea level to 10km) such that the ambient temperature and the air density decrease. I need to know the rate of heat flux.
I tried to solve this problem by calculating the Prandtl...
