Electric heater wires are installed in a solid wall having a thickness of 8 cm and k=2.5W/m- °C. The right face is exposed to an environment with h=50W/m^ 2 . C and T infty =30^ C , while the left face is exposed to h=75 W/m^ 2 C T infty =50^ C . What is the maximum allowable heat-generation rate such that the maximum tem perature in the solid does not exceed 300 degrees * C ?

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.
