23.2. Energy is generated at a constant rate of 104Wm3 throughout a slab of thickness 10cm and constant thermal conductivity 1.2Wm1K1. The boundary surface on one side is insulated so that there is no heat flow across this boundary, and on the other dissipates heat by convection into a fluid at temperature 20C with a heat transfer coefficient 74Wm2K1. Calculate the steady state temperature at both surfaces of the slab, and the heat flux from the slab into the fluid. Sketch the temperature profile and heat flux profile through the slab. (N.B. The heat flux can be calculated in three ways - from the temperature profile at the slab surface, from the convection heat transfer equation, and one other way-what is it?)
