A uniform internal energy generation occurs in a plane wall with a thickness of 60 mm and a constant thermal conductivity of 3W / m. K. For these conditions, the temperature distribution has the form T (x) = a + bx + c x?. The surface at x = 0 has a temperature = T = 110 ° C and experiences convection with a fluid for which To = 25 ° C and h = 300 W / m². K. The surface at x = L is well insulated. For one - dimensional, steady - state conduction (a) calculate the volumetric energy generation rate. (b) determine the coefficients a, b, and c by applying the boundary conditions to the prescribed temperature distribution.

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.
