An vacant ball is made of aluminum (k = 202 W/m. "C) with an inner diameter of 4 cm and an outer diameter of 8 cm. The internal temperature is 100°C and If the ball above is coated with an insulating material having k = 50 mW/m.°C 1 cm thick The outside of this insulation is in contact with an environment having h = 20 W/m.°C and Ts = 10°C, calculate the heat transfer under these conditions.

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.
