A radioactive material that is very long in the y direction and with a thickness of L in the x direction produces u" of heat per unit volume. The left side of this material (x=0) is perfectly insulated, and on the right side (x=L), a fluid with an infinite temperature T and a convective heat transfer coefficient h flows. Find an expression that gives the one-dimensional temperature distribution (T(x)) in this substance. Also, calculate how much heat is transferred per unit area from the material to the fluid flowing on its right side.
