A hollow cylinder with inner radius of 30 mm and outer radius of 50 mm is heated at the inner surface at a rate of 10^5m^2W​ and dissipated heat by convection from outer surface into a fluid at 80∘C with h=400 m2 KW​. There is no energy generation and thermal conductivity of the material is constant at 15mKW​. Calculate the temperature of inside and outside surfaces of cylinder.
