A long pipe carries hot water and loses heat by convection to the surrounding air at Too=16 °C and h=20 W/(m2°C). The pipe has a thermal conductivity of k=1.7 W/(m°C), inner radius of r1=0.2 m and outer radius of r2=0.22 m. Assume that the inner surface temperature of pipe is T1=53°C. If there is no heat generation in the pipe material, calculate the outer surface temperature of the pipe T(r2), in °C, by considering steady one-dimensional heat transfer and constant thermal conductivity.

Heat transfer
![A long pipe carries hot water and loses heat by convection to the surrounding air at Too-16
°C and h=20 W/(m2°C). The pipe has a thermal conductivity of k=1.7 W/(m°C), inner radius
of r1=0.2 m and outer radius of r2=0.22 m. Assume that the inner surface temperature of
pipe is T1=53°C. If there is no heat generation in the pipe material, calculate the outer
surface temperature of the pipe T(r2), in °C, by considering steady one-dimensional heat
transfer and constant thermal conductivity.
