Spherical heat conduction

WebThe general heat conduction equation in spherical co-ordinates can be set up by considering an infinitesimal spherical volume element- dV = (dr × rdɸ × r sin ϴ dɸ) and writing the heat … WebHeat loss by conduction is negligible. Heat loss by convection (i.e. due to air currents or wind) will be dependent upon the geographic location of the conductor 100. A conductor 100 may be deployed in a hot region of the world such as Southern USA, the Middle East or Australia. Winds in non-coastal regions may be relatively light and hence ...
