Week $5$: Radial Conduction

Water at $63C$ flows through a steel pipe with a

$7$ cm inner diameter and a $2$ cm thick wall. The

pipe is covered with a $6$ cm thick layer of

insulation. The air surrounding the pipe is at

$20C.$ The convection coefficient on the inside

of the pipe is $1,141\frac{W}{m^2}*K.$ On the outside,

the convection coefficient is $11\frac{W}{m^2}.$ K $.$

Complete a dimensioned and labeled

sketch of the cross section of the pipe.

Overlay your sketch with the thermal

resistance network for heat transfer

between the water inside and the air

outside of the tube. $\{$Include sketch with

support work$\}$

For a $1$ m long pipe, calculate the heat loss

rate. $\{$Include calculations with support

work$\}$

Calculate the temperature at the

interface between the pipe wall and the

insulation. $\{$Include calculations with

support work$\}$
