= = A hollow sphere of inner radius r1 = 30 cm and outer radius r2 50 cm is heated at the inner surface. The temperature at the inside and outside surfaces of the sphere is T1 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: I J-T2 P=4nkrir 2 r 2-r1 .(b) The difference of temperature between two surfaces of the sphere is 7.0°C. Find the rate of heat flow out of the sphere
