Answer 1

In the case of turbulent flow through a horizontal isothermal cylinder having diameter 'd', the free convection heat transfer coefficient from the cylinder will be independent of the diameter.

• The coefficient of heat transfer coefficient rests on the medium's thermal properties, as well as the hydrodynamic properties of the flow.
• The average heat transfer coefficient is equal to the heat flow divided by the temperature. Thus, during the heat transfer in an isothermal cylinder, the cylinder will be  independent of the diameter.
