Answer» A hollow cylindrical pipe of length $10 cm$ has inner radius $r_{1} = 3 cm$ and outer radius $r_{2} = 12 cm$ . The temperature difference between the inner and outer layer of cylindrical pipe is $100^{\circ} C$ and the thermal conductivity of cylindrical pipe is $150 {W/m}^{\circ} C$ . Find the rate of heat transfered (in $kW$ ) between inner and outer layers. (Take $ln 2 = 0.693$ )
