Heat Transfer in a Solid Using Equation of Energy Change. A solid of thickness L is at a uniform temperature of To K. Suddenly the front surface temperature of the solid at z = 0 m is raised to T at i = 0 and held there and at z = L at the rear to T, and held constant. Heat transfer occurs only in the z direction. For constant physical properties and using the differential equation of energy change, do as follows. (a) Derive the partial differential equation and the boundary conditions for unsteady-state energy transfer. (b) Do the same for steady state and integrate the final equation.

Heat Transfer in a Solid Using Equation of Energy Change. A solid of thickness L is at a uniform temperature of To K. Suddenly the front surface temperature of the solid at z = 0 m is raised to T at i = 0 and held there and at z = L at the rear to T, and held constant. Heat transfer occurs only in the z direction. For constant physical properties and using the differential equation of energy change, do as follows. (a) Derive the partial differential equation and the boundary conditions for unsteady-state energy transfer. (b) Do the same for steady state and integrate the final equation.
2. Heat Transfer in a Solid Using Equation of Energy Change. A solid of thickness
L is at a uniform temperature of T, K. Suddenly the front surface temperature
of the solid at z = 0 m is raised to T; at t =
z = L at the rear to T2 and held constant. Heat transfer occurs only in the
z direction. For constant physical properties and using the differential equation
of energy change, do as follows.
(a) Derive the partial differential equation and the boundary conditions for
unsteady-state energy transfer.
(b) Do the same for steady state and integrate the final equation.
