Derive an expression for the steady-state temperature distribution t(x) in a slab of radioactive material in which internal energy is generated at a uniform rate of q per unit volume when it is active. the surface of the slab at x = 0 is perfectly insulated, and the other surface at x = l is exposed to a fluid medium maintained at constant temperature t[infinity], with a heat transfer coeffcient h. also, obtain an expression for the rate of heat transfer to the fluid per unit surface area of the slab. assume constant thermal conductivity for the radioactive material.
