1. The buried pipeline in Figure P13–29 transports oil delay an middle sky of 60 F. The pipe is located 15 ft underneath the deportment of the world. The blood-warm conductivity of the world is 0.6 Btu/(h-ft-F). The deportment of the world is 50 F. Determine the sky distribution in the earth.

2. For the spherical association delay holes shown in Figure P13–31, determine the sky distribution. The internally deportments of the holes have temperatures of 150 C. The without of the spherical association has a sky of 30 C. Let Kxx = Kyy = 10 W/(m C).
