An exothermic reaction takes place in a long cylinder of radius 40 mm with a thermal conductivity of 6.5 W/mK which leads to the generation of heat uniformly in the volume. If the allowed
temperature difference between the surface and the center is 246°C, determine the heat generation rate possible. Also find the required value of convection coefficient to dissipate the heat to a
fluid at 100°C, with the surface temperature to be at 150°C
