Heat is generated uniformly by chemical reaction in a sphere of
radius 40 mm. The conductivity
of the material is 6.5 W/mK. If the allowable temperature rise at the center over the surface is
246°C, determine the heat generation rate. If the surface temperature is 150°C and if a fluid at
100°C is used to collect the heat, determine the required value of convection coefficient
