Question
A hot water pipe is 100 mm in diameter and 80 m long. This pipe is insulated in two layers.
First layer is 25 mm thick, thermal conductivity is 0.12 W/m C material, second layer is 45 mm thick
It is made of material with a thermal conductivity of 0.05 W/m C. T1, T2 and T3 are the surface
temperatures in the pipe. One
With the acceptance of heat transfer in dimensional and continuous conditions, transfer from the
pipe in case T1= 600 OC and T3= 35 C
Find the amount of heat released and the temperature T2.
