$8\mathrm{.}31$ To cool a summer home without using a vaporcompression refrigeration cycle, air is routed through a plastic pipe $0\mathrm{.}17$ m $)$ that is submerged in an adjoining body of water. The water temperature is nominally at $T_{}=17C,$ and a convection coefficient of $h_o$~~$1500\frac{W}{m^2}*K$ is maintained at the outer surface of the pipe.

If air from the home enters the pipe at a temperature of $T_{m,i}=29C$ and a volumetric flow rate of $A{A}_i=0\mathrm{.}025\frac{m^3}{s},$
