Required information

A $10-$m$-$long section of a $5-$cm$-$diameter horizontal hot$-$water pipe passes through a large room whose temperature is $\backslash (27^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash ).$ The temperature and the emissivity of the outer surface of the pipe are $\backslash (73^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash )$ and $0\mathrm{.}8,$ respectively. Use the property tables to calculate the properties of air at the film temperature.

Determine the rate of heat loss from the pipe by natural convection.

The rate of heat loss from the pipe is
