Problem $02\mathrm{.}071$E $-$ Heat Conduction in a Steam Pipe $-$ DEPENDENT MULTI$-$PART PROBLEM $-$ ASSIGN ALL PARTS

Consider a steam pipe of length $L=35ft,$ inner radius $r_1=2in,$ outer radius $r_2=2\mathrm{.}4in,$ and thermal conductivity $k=7\mathrm{.}2Bt\frac{u}{h}*ft*F.$ Steam is flowing through the pipe at an average temperature of $250F,$ and the average convection heat transfer coefficient on the inner surface is given to be $h=12\mathrm{.}5Bt\frac{u}{h}*f{t}^2*F.$ The average temperature on the outer surface of the pipe is $T_2=160F.$

NOTE: This is a multi$-$part question. Once an answer is submitted, you will be unable to return to this part.

Problem $02\mathrm{.}071$E$.$c $-$ Rate of Heat Loss in the Pipe

Evaluate the rate of heat loss from the steam through the pipe.

The rate of heat loss from the steam through the pipe is $$ Btu$/$h$.$
