A hollow sphere of inner radius n = 30 cm and outer radius r= 50 cm is heated at the inner surface. The rate of heat flow out of the sphere is 11.30 kW. The temperature at the inside and outside surfaces of the sphere is T and T2. The thermal conductivity of the material is k = 170 W(m.K)'. (a) Demonstrate that the rate of heat conduction is computed by the formula: P=4.7kr,nT-T (b) Find the difference of temperature between two surfaces of the sphere.
