Ok, sometimes the semi-infinite approach is about long times with semi-infinite geometries. The ground at northernclimates with sustained low temperatures will freeze to a certain depth, something to be aware of when burying waterpipes. Say an area exists where temperatures of -10°C can be sustained at the ground surface for up to 45 days. Howdeep should pipes be buried to keep from exposing them to freezing temperatures? Assume the ground starts at auniform 5°C. For the soil, use a thermal conductivity k of 0.35 W/m∙K and a thermal diffusivity  of 1.5 x 10-7 m2/s.
