Q1) The wall of a drying oven is constructed by sandwiching an insulation material of thermal conductivity k=0.05 W/m K between thin metal sheets in which heat is generated uniformly at a rate of 2x10 W/m. The oven air is at T-300°C, and the corresponding convection coefficient is h-30 overall coefficient for convection and radiation from the outer surface is ho=10W/m² K.

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.
