For the following geometry, plot the total resistance, conductive

resistance, and convective resistance as a function of $R_3$ from $0\mathrm{.}1$ to

$10mm.R_1=5\mathrm{.}25cm,R_2=6cm.$ The inner pipe has $43\frac{W}{m}*K.$ The

insulation material has $k=0\mathrm{.}06\frac{W}{m}*K.L=1m.$ The inner pipe

surface is at $150$@$C$ and the exterior surface of the insulation is at

$25$@ C$.$ Plot the heat loss as a function of changing the insulation

thickness from $0\mathrm{.}1$ mm to $100$ mm $.$
