Tec Exa Consider the following configuration of fins that are attached to a surface with a thermal conductivity (k) of 311 W/mK and a base temperature of 156 "C. The thermal conductivity of the fins is the same as that of the surface. The temperature of the air surrounding the fins is 25 °C. and the heat transfer coefficient on the air-side is 56 W/m²K. Assume the fin tips are adiabatic. Fin the following: SL D) ii) the heat flowrate per m² of the surface the fin effectiveness Temperature of base=456 C x = Fin center-to-center distance = 15 mm Fin diameter = 5 mm Fin height= 50 mm Fin arrangement details

Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.
