Consider a slab of thickness I. and constant thermal conductivity k in which energy is generated at a constant rate of go W/m³. the boundary surface at x = 0 is insulated (adiabatic) and that at x = L dissipates heat by convection with a heat transfer coefficient h into a fluid at a temperature T. Develop expressions for the temperature T(x) and the heat flux q(x) in the slab. Calculate the temperatures at the surface x = 0 and x = L under the following conditions: L 1cm; k= 20 W/m °C, g = 8 x 10 W/m³, h = 400 W/m² °C, and T = 100 °C

4) Consider a slab of thickness L. and constant thermal conductivity k in which energy is generated at a constant rate of go W/m³. the boundary surface at x = 0 is insulated (adiabatic) and that at x = L dissipates heat by convection with a heat transfer coefficient h into a fluid at a temperature To. Develop expressions for the temperature T(x) and the heat flux q(x) in the slab. Calculate the temperatures at the surface x = 0 and x = L under the following conditions: L = 1cm; k = 20 W/m °C, go = 8 x 107 W/m³, h = 400 W/m² °C, and T = 100 °C
