The heat generating rate per unit volume qg, at any radius r of a solid rod is given by qg=qo(1-(r/R)^2) where qo is the heat generation rate at the center of the rod of radius R. Find out an expression for maxium temperature at the center of a rod 40 cm diameter , when heat generating rate at the center is 24(10^6) KJ/m^3 -h and temperature at the surface of the rod is 20 C. Assume k for the material of the rod as 200 KJ/m-h-C
